命令格式简介
stata命令格式
[by varlist:] command [varlist] [=exp] [if exp] [in range] [weight] [, options]
1。Command 命令动词,经常用缩写。 2。varlist 表示一个变量或者多个变量,多 个变量之间用空格隔开。如 sum price weight
添加标签
打开wage1数据文件。 1。为整个数据添加标签:例如,将数据命名为“工 资表”。
菜单:Data->Labels->Label dataset 命令:label data “工资表“ 2。为变量增加标签,例如,给变量wage增加标签 “年工资总额” 菜单:Data->Labels->Label variables 命令 label variable wage “年工资总额”
summarize---sum describe------des 得到正确命令缩写的简单方法:看help。
几条最简单的命令
use 打开数据文件,一般加clear选型清空 内存中现有数据。 sysuse 打开系统数据文件。 describe 描述数据 edit 利用数据编辑器进行数据编辑 list 类似于edit,但只能显示不能修改数据。

Stata12软件的基本设定(设置)

Stata12软件的基本设定(设置)

Stata12软件的基本设定如果你已经安装了stata12,请直接跳到(6)。

(1)将StataSE12.1绿色版.7z解压到D盘根目录,即D:\stata12(注意:是D:\stata12,而非D:\stata12\stata12,另外,stata12是小写)。

(下载地址:/share/link?shareid=2683949182&uk=3523563089)1(2)打开stata12:双击图1中带有蓝色阴影的图标即可。

图1 stata12放置界面(3)关于更新A、首次打开stata12,会弹出对话框,询问你是否需要更新。

如果不需要更新,请按下图进行设定:图2 首次打开stata12时的更新设定B、(为了节省时间,这一步可以跳过,对于一般用户而言,更新与否不会影响你的使用效果)如需把stata12更新到最新版本,请在command窗口中输入update al l命令。

更新过程大概需要几分钟到几十分钟不等。

特别注意的是,更新完毕后,你一定要输入如下命令,才算是真正完成了stata的更新:updateswap。

这个命令的作用是用新下载的文件覆盖旧文件。

忘记这一步,往往会导致你的stata丢失变量或出现一些奇怪的现象。

1你也可以右击这个图标,然后选择“附加到开始菜单”。

这样stata12的logo就会出现在开始菜单中,每次启动stata12就只需从“开始”菜单中单击这个logo即可。

(4)关于profile.do文件。

每次启动stata12时,它会自动执行D:\stata12文件夹下的p rofile.do文件,该文件中包含了一系列命令,用于设定stata所占用的内存,各种文件路径的位置等信息。

如果你是按照上述要求放置stata12文件的,那么启动stata12后,屏幕上应该显示如下信息(否则你要检查文件名的拼写是否正确):running D:\stata12\pro fi le.d o...(5)如果你的计算机分区中没有D盘,你也可以把stata12放置于其他盘符下,但需要做一些微小的调整。

三、数据的使用与基本描述(打开数据)
• STATA可以使用多种数据各式,但是命令不同。 其中,.dta是STATA特有的数据各式。常用的数据 命令有两个: • 当数据不是STATA格式时,用insheet命令,就是 让STATA将using后路径的数据放到STATA的数据 sheet中: insheet using $rawdata\finance.csv,clear **后面的,clear后缀,是说如果之前数据库中有其 他 数据,就要先清楚其他数据,再将新数据输入。 • 如果是STATA各式数据,则采用use命令: use $rawdata\finance.dta,clear
4
二、do 文件(cont')
why do file?
重复运行,便于检查错误
Example: /*This program is written for the econometrics class of 27/09/12. */ clear all <清空内存数据> set mem 100m <设定内存100m> set maxvar 5000 <最大变量个数5000个> set more off cd C:\ccer\ln <进入某路径> capture log close < > log using logfile\*****.log,replace < > ............... capture log close < >

§ (3)计算模型预测的百分比来计算模型的 拟合优度。
§ 如果要检验这个分类的依据或者要获得每个预测值,可以 利用此二值模型进行预测分析,Stata中二值选择模型的 预测的命令语句如下所示: § predict [type] newvar [if] [in] [,single_options] § 其中predict是表示对模型进行预测的命令;newvar表示 预测新变量的名称,type可以表明设定新变量的类型;if 和in表示对此预测设定的条件和范围;single_options的 内容以下表所示:
§ 由于logit与probit模型得出的参数估计值不可直接 比较,根据本节开始介绍的原理已了解到两模型 的边际效应可以比较。Stata中probit模型的边际 效应得出方法与logit是相同的。 § 在Stata命令窗口中输入如下命令计算probit模型 回归后解释变量在样本均值处的边际效应: § mfx § 可以看到与前面的logit模型比较,两模型分析的 边际效应是大致相同的。然后来计算probit模型 的拟合优度,具体操作方法也与logit模型是一致 的。
§ (2)由于估计系数不像线性模型能够表示解释变量的边 际效应,所以Stata中有额外的命令语句来计算解释变量 的边际效应: § mfx [compute] [if] [in] [,options] § 此命令语句中mfx表示对回归之后的模型计算解释变量的 边际效应,其中options内容如下表所示:
§ 2.建立probit模型分析 § 前面是使用logit模型对womenwork.dta进行分析, 现在使用probit模型对此问题进行分析。两种方 法在Stata中的操作是很一致的。 § 在Stata命令窗口中输入如下命令: § use womenwork, clear § 使用此命令打开所需要文件。 § probit work age education married children § 此命令表示使用probit模型进行回归。 § § 此图的解读方法与Logit模型结果图是完全一样的, probit模型估计结果显示系数估计值相比logit估计 值发生了很大变化,且均显著通过了模型系数的 显著性检验;另外模型的准R2是0.1889,相比 logit模型稍有改进。

4Getting helpSystem helpStata’s help system provides a wealth of information to help you learn and use Stata.Tofind out which Stata command will perform the statistical or data management task you would like to do,you should generally follow these steps:1.Select Help>Search...,choose Search all,and enter the topic or keywords.This searchwill open a new Viewer window containing information about Stata commands,references to articles in the Stata Journal,links to Frequently Asked Questions(FAQ s)on Stata’s website, links to videos on Stata’s YouTube channel,links to selected external websites,and links to community-contributed features.2.Read through the results.If youfind a useful command,click on the link to the appropriatecommand name to open its helpfile.3.Read the helpfile for the command you chose.4.If you want more in-depth help,click on the link from the name of the command to the PDFdocumentation,read it,then come back to Stata.5.If thefirst helpfile you went to is not what you wanted,either click on the Also see menuand choose a link to related helpfiles or click on the Back button to go back to the previous document and go from there to other helpfiles.6.With the helpfile open,click on the Command window and enter the command,or click onthe Dialog button and choose a link to open a dialog for the command.7.If,at any time,you want to begin again with a new search,enter the new search terms in thesearch box of the Viewer window.8.If you select Search documentation and FAQs,Stata searches its keyword database for officialStata commands,Stata Journal articles and software,FAQ s,and videos.If you select Search net resources,Stata searches for community-contributed commands,whether they are from the Stata Journal or elsewhere;see[GSM]19Updating and extending Stata—Internet functionality for more information.Let’s illustrate the help system with an example.You will get the most benefit from the example if you work along at your computer.Suppose that we have been given a dataset about antique cars and that we need to know what it contains.Though we still have a vague notion of having seen something like this while working through the example session in[GSM]1Introducing Stata—sample session,we do not remember the proper command.Start by typing sysuse auto,clear in the Command window to bring the dataset into memory.(See[GSM]5Opening and saving Stata datasets for information on the clear option.) Follow the above approach:1.Select Help>Search....2.Check that the Search all radio button is selected.3.Type dataset contents into the search box and click on OK or press Return.Before wepress Return,the window should look like12[GSM]4Getting help4.Stata will now search for“dataset contents”among the Stata commands,the reference manuals,the Stata Journal,the FAQ s on Stata’s website,and community-contributed features.Here is the result:[GSM]4Getting help3 5.Upon seeing the results of the search,we see two commands that look promising:codebookand describe.Because we are interested in the contents of the dataset,we decide to check out the codebook command.The[D]means that we could look up the codebook command in the Data Management Reference Manual.The codebook link in(help codebook)means that there is a system helpfile for the codebook command.This is what we are interested in right now.6.Click on the codebook link.Links can take you to a variety of resources,such as help for Statacommands,dialogs,and even webpages.Here the link goes to the helpfile for the codebook command.7.What is displayed is typical for help for a Stata command.Helpfiles for Stata commandscontain,from top to bottom,these features:a.The quick access toolbar with three buttons:i.The Dialog button shows links to any dialogs associated with the command.ii.The Also see button shows links to related PDF documentation and helpfiles.iii.The Jump to button shows links to other sections within the current helpfile.b.The second line of a helpfile shows a View complete PDF manual entry link.Clicking on the link will open the complete documentation for the command—in this case,codebook—in your PDF viewer.c.The command’s syntax,that is,rules for constructing a command that Stata will correctlyinterpret.The square brackets here indicate that all the arguments to codebook are optional but that if we wanted to specify them,we could use a varlist,an if qualifier,or an in qualifier,along with some options.(Options vary greatly from command to command.) The options are listed directly under the command and are explained in some detail later in the helpfile.You will learn more about command syntax in[GSM]10Listing data and basic command syntax.4[GSM]4Getting helpd.A description of the command.Because“codebook”is the name for big binders containinga hard copy describing each of the elements of a dataset,the description for the codebookcommand is justifiably terse.e.The options that can be used with this command.These are explained in much greaterdetail than in the listing of the possible options after the syntax.Here,for example,we cansee that the mv option can look to see if there is a pattern in the missing values—somethingimportant for data cleaning and imputation.f.Examples of command usage.The codebook examples are real examples that step throughusing the command on a dataset either shipped with Stata or loadable within Stata fromthe Internet.g.The information the command stores in the returned results.These results are usedprimarily by programmers.For now,either click on Jump to and choose Examples from the drop-down menu or scroll down to the examples.It is worth going through the examples as given in the helpfile.Here is a screenshot of the top of the examples:[GSM]4Getting help5 Searching helpSearch is designed to help youfind information about statistics,graphics,data management,and programming features in Stata,either as part of the official release or as community-contributed features.When entering topics for the search,use appropriate terms from statistics,etc.For example,you could enter Mann-Whitney.Multiple topic words are allowed,for example,regression residuals.When you are using Search,use proper English and proper statistical terminology.If you already know the name of the Stata command and want to go directly to its helpfile,select Help>Stata command...and type the command name.You can also type the command name in the Searchfield at the top of the Viewer and press Return.Help distinguishes between topics and Stata commands because some names of Stata commands are also general topic names.For example,logistic is a Stata command.If you choose Stata command...and type logistic,you will go right to the helpfile for the command.But if you choose Search...and type logistic,you will get search results listing the many Stata commands that relate to logistic regression.Remember that you can search for help from within a Viewer window by typing a command in the command box of the Viewer or by clicking the magnifying glass button to the left of the search box,selecting the scope of your search,typing the search criteria in the search box,and pressing Return.Help and search commandsAs you might expect,the help system is accessible from the Command window.This feature is especially convenient when you need help on a particular Stata command.Here is a short listing of the various commands you can use:•Typing help commandname is equivalent to selecting Help>Stata command...and typing commandname.The helpfile for the command appears in a new Viewer tab.•Typing search topic in the Command window produces the same output as selecting Help> Search...,choosing Search all,and typing topic.The output appears in a new Viewer tab.•Typing search topic,local in the Command window produces the same output as selecting Help>Search...,choosing Search documentation and FAQs,and typing topic.The output appears in the Results window instead of a Viewer.•Typing search topic,net in the Command window produces the same output as selecting Help>Search...,choosing Search net resources,and typing topic.The output appears in the Results window instead of a Viewer.See[U]4Stata’s help and search facilities and[U]4.8search:All the details in the User’s Guide for more information about these command-language versions of the help system.The search command,in particular,has a few capabilities(such as author searches)that we have not demonstrated here.The Stata reference manuals and User’s GuideAll the Stata reference manuals come as PDFfiles and are included with the software.The manuals themselves have many cross-references in the form of clickable links,so you can easily read the documentation in a nonlinear way.Many of the links in the helpfiles point to the PDF manuals that came with Stata.It is worth clicking on these links to read the extensive information found in the manuals.The Stata help system, though extensive,contains only a fraction of the information found in the manuals.6[GSM]4Getting helpMost Stata reference manuals are each arranged alphabetically.Each Getting Started with Stata has its own index.A combined index for all other manuals can be found in the Stata Index.This combined index is a good place to start when you are looking for information about a command.Entries have names like collapse,egen,and summarize,which are generally themselves Stata commands.Notations such

stata12毕设速成手册

stata12毕设速成手册

随便网上一搜就好多Stata使用说明,但大家估计都不想细细看,所以我按自己使用Stata 的经验按一般的操作顺序写了速成手册。

声明:本帖只适合为了毕设才刚接触Stata的人,任何入过门的走过路过请错过!福利帖,废话不多说。

我使用的是Stata 12绿色版,不需安装,直接点击Stata SE.exe即可使用。

本手册简单,更详细内容可参见“stata使用手册.pdf”。

1、打开界面,导入数据数据处理包含两层结构,一个是操作界面,如下所示。

另一个是数据表,见下图,有两种方式打开:1. Command命令框中输入bro或者edit,这两个命令的区别在于前者打开后处于浏览模式,不能进行数据更改,而后者可以随意更改。

2. 点击操作界面的图标(如上所示),直接进入编辑模式。

2. 如何输入数据并保存正常大家下载的数据都是excel格式的,导入数据有很多方法,最直接也是我用的最多的就是复制-粘贴。

Excel中复制,到数据表界面右击最左上一格选粘贴。

这时候会提醒“treat firstrow as data”还是“treat first row as variable names”,选后者即可。

粘贴后的例子如下所示:这时候我们就发现右边Variables中显示出了当前表中的所有变量了。

这里注意两点:1. 变量名必须是英文的;2. 变量表不能是二维的,在上述表中,一个日期对应一条记录,这是一维的。

如果是一个日期、一个地点对应一条记录,那表只能采用如下格式:而不能是如下格式可以在原来粘贴的基础上继续粘贴,就跟excel里面粘贴一样。

之后关闭程序,就提醒你保存了,或者在command里面输入:save 英文文件名,然后回车。

3. 操作命令在操作命令的命令框中,可以输入指令结合相应变量名,然后按回车进行操作,最简单的就是上述的bro和edit。

所有的命令当你不知道怎么书写格式时,在command中输入:help 命令,就可以查看操作方式了。

STATA基本功能介绍_266605879

STATA 基本功能介绍命令历史记录结果及运行过程显示窗口变量命令输入窗口一 STATA的基本文件格式1.数据集:以 .dta 为后缀2.命令文件:以 .do 为后缀3.运行结果:以 .log 或 .smcl 为后缀二 STATA的基本命令1.打开数据集:有两种方法,一是直接从工具栏打开。

二是从命令输入窗口输入命令打开,命令为use例子: use "D:\Stata10\auto.dta", clear该例子中,表示把位于”D:\Stata10”这个文件夹下的auto.dta这个数据文件打开。

逗号后为选项,clear表示在打开auto.dta的同时将原来打开的文件从内存中清空。

2.保存数据集:从命令输入窗口输入命令保存,命令为save例子:save “D:\Stata10\example.dta”, replace该例子中,我们把打开的数据集保存在了”D:\Stata10”下,同时重新命名该数据集为example.dta。

replace 是选项,表示覆盖同一文件夹下同样名称的数据集。

3.创建新变量:generate例子: generate revenue=price*quantity这个例子中,我们创建了一个新变量,revenue。

新变量等于已有变量price 乘以 quantity。

4.删除变量或观察值:drop例子1:drop revenue例子1中,把revenue这个变量全部从数据集中删除。

例子2:drop if revenue > 500例子2中,是把所有revenue大于500的观测值都从数据集中删除。

请注意例子1和例子2的差别。

5.替代原有变量:replace例子1:replace price=2 (把原来变量price中的所有值替代成2)例子2:replace price=quantity (把变量price中的所有值替代成变量quantity中的值)例子3:replace price=price*2 (把变量price中的所有值替代成原有值的两倍)6.计算基本统计量:summarize例子1:summarize priceVariable | Obs Mean Std.

Stata软件基本操作和数据分析入门

Stata软件基本操作和数据分析入门

Stata软件基本操作和数据分析入门第一讲Stata操作入门张文彤赵耐青第一节概况Stata最初由美国计算机资源中心(Computer Resource Center)研制,现在为Stata公司的产品,其最新版本为7.0版。

它操作灵活、简单、易学易用,是一个非常有特色的统计分析软件,现在已越来越受到人们的重视和欢迎,并且和SAS、SPSS一起,被称为新的三大权威统计软件。

Stata最为突出的特点是短小精悍、功能强大,其最新的7.0版整个系统只有10M左右,但已经包含了全部的统计分析、数据管理和绘图等功能,尤其是他的统计分析功能极为全面,比起1G以上大小的SAS系统也毫不逊色。

另外,由于Stata在分析时是将数据全部读入内存,在计算全部完成后才和磁盘交换数据,因此运算速度极快。

由于Stata的用户群始终定位于专业统计分析人员,因此他的操作方式也别具一格,在Windows席卷天下的时代,他一直坚持使用命令行/程序操作方式,拒不推出菜单操作系统。

但是,Stata的命令语句极为简洁明快,而且在统计分析命令的设置上又非常有条理,它将相同类型的统计模型均归在同一个命令族下,而不同命令族又可以使用相同功能的选项,这使得用户学习时极易上手。

更为令人叹服的是,Stata语句在简洁的同时又拥有着极高的灵活性,用户可以充分发挥自己的聪明才智,熟练应用各种技巧,真正做到随心所欲。

除了操作方式简洁外,Stata的用户接口在其他方面也做得非常简洁,数据格式简单,分析结果输出简洁明快,易于阅读,这一切都使得Stata成为非常适合于进行统计教学的统计软件。

Stata的另一个特点是他的许多高级统计模块均是编程人员用其宏语言写成的程序文件(ADO文件),这些文件可以自行修改、添加和下载。

用户可随时到Stata网站寻找并下载最新的升级文件。

事实上,Stata的这一特点使得他始终处于统计分析方法发展的最前沿,用户几乎总是能很快找到最新统计算法的Stata程序版本,而这也使得Stata自身成了几大统计软件中升级最多、最频繁的一个。

stata使用手册资料

stata使用手册资料

STATA基本入门前言STATA是一个十分好用而且简单的统计软件包,透过轻松的数据输入方式,而且简单的指令,即可执行一般在计量经济学上常用的计量模型。

除了计量模型外,STATA的软件包中也可执行统计学中的估计和检定,甚至是多变量分析中的各项分析工具。

因此,STATA可以说是一个相当强而有力的统计软件。

一、安装STATA所须的内存容量不大,只有。

此外,安装也相当简单,只要在〝SETUP〞上点两下,安装完成后再分别输入”Sn”、”Code”和”Key”即可开始使用。

但是安装过程中有一点必须注意的是,如下图所示,有”Intercooled”和”Small”两个选项。

一般而言,为了方便日后要设定较大的内存容量来处理大笔的资料,通常选择以”Intercooled”进行安装。

以此項進行安裝二、窗口介绍安装完成后,点选桌面上STATA的图标,窗口画面如下图所示。

为了使画面美观,我们可以将画面拉到自己喜欢的地方,如下图所示。

为了保存这个窗口画面,我们必须点选工具列上的”Prefs”下的”Save Windowing Preferences”。

如此一来,以后开启STATA 时都会以此窗口画面呈现。

指令的執行結果看這裡執行過的指令都會保留於此 資料中的變數在這裡在此輸入指令接下来,我们依序介绍四个窗口的功用:左上─Review:此一窗口用于记录在开启STATA后所执行过的所有指令。

因此,若欲使用重复的指令时,只要在该指令上点选两下即可执行相同的指令;若欲使用类似的指令时,在该指令上点一下,该指令即会出现在窗口”Stata Command”上,再进行修改即可。

此外,STATA还可以将执行过的指令储存下来,存在一个do-file内,下次即可再执行相同的指令。

左下─Variables:此一窗口用于呈现某笔数据中的所有变量。

换言之,当数据中的变量都有其名称时,变量名称将会出现在此一窗口中。

只要数据有读进STATA中,变量名称就会出现。

(3)关于更新
A 、首次打开 stata12,会弹出对话框,询问你是否需要更新。

如果不需要更新,请按下
图进行设定:
图 2首次打开stata12 时的更新设定B(、为了节省时间,这一步可以跳过,对于一般用户而言,更新与否不会影响你的使
用效果)如需把stata12 更新到最新版本,请在command窗口中输入updateal l命令。

更新过程大概需要几分钟到几十分钟不等。

特别注意的是,更新完毕后,你一定要输入如下
命令,才算是真正完成了stata 的更新: updateswap。

这个命令的作用是用新下载的文件覆盖
旧文件。

忘记这一步,往往会导致你的stata 丢失变量或出现一些奇怪的现象。

1
你也可以右击这个图标,然后选择“附加到开始菜单”。

这样 stata12 的 logo 就会出现在开始
菜单中,每次启动 stata12 就只需从“开始”菜单中单击这个 logo 即可。

(4)关于profile.do文件。

每次启动stata12 时,它会自动执行D:\stata12 文件夹下的 profile.do文件,该文件中包含了一系列命令,用于设定stata所占用的内存,各种
文件路径的位置等信息。

如果你是按照上述要求放置stata12 文件的,那么启动
stata12 后,屏幕上应该显示如下信息(否则你要检查文件名的拼写是否正确):running stata12 profi le .do...
( 5)如果你的计算机分区中没有 D 盘,你也可以把stata12 放置于其他盘符下,但需要做一些微小的调整。

这里以 F 盘为例,也可以是C, H, K 等其他盘
①.将 stata12 解压后放置于 F 盘下,即F:\stata12 。

注意: stata 是小写。

②.修改 profile.do 文件,具体方法为 :
Step1: 输入 doedit F:\stata12 \prof il e. do命令,打开 profile.do 文件; Step2:将第六行
中的 localD"D" 命令修改为 l ocal D"F";
Step3:保存 profile.do文件,退出stata12,然后重启即可。

③.若上述设定无误,则在重新打开stata12 后,屏幕第一行会显示如下信息:
running stata12profi le .d o...
同时,输入sysdir命令,屏幕上会呈现如下信息( 此时你才能正确使用外部命令):
.sy sdir
STATA: F stata12
UPDATES: F stata12 \ado\updat BASE:
F stata12 \ado\bas SIT E:
F stata12 \ado\s it PLUS:
F stata12 \ado\p
PERSONAL: F stata12 \ado\personal
PartII :课件的使用方法
Q1. 如何打开课堂上使用的do 文档?
A:请将PX_aufe.rar压缩包解压到D:\stata12\ado\personal 文件夹中,即
D:\stata12\ado\personal\PX_aufe 。

若希望练习第一讲中的相关操作,可依次执行如下命令:Step1:在STATA命令窗口中输入cdD:\stata12\ado\personal\PX_aufe命令,定义当前工作
路径(会显示在 STATA 屏幕左下角);
Step2:输入doedit xB01_Panel_Data命令,即可打开第一讲的讲义

Q2. 如何查看每次执行STATA 的 log 文件?
A:我在profile.do文件中进行了设定,每次启动STATA12后,屏幕上呈现的所有结果都
会被自动记录到一个日志文件中。

这些日志文件被自动保存在D:\stata12\do 文件夹下,文件名称为打开STATA 时的时间,例如,名称为 s22Apr2010111857.txt 的日志文件是我在2010 年 4 月22 日 11 点 18 分 57 秒打开 STATA12 时自动生成的。

Q3. 如何正确显示中文字符?
A:在默认设定下,首次打开 Stata12 时,所有的窗口都是白色的,此时 Stata12 无法正常显示中文字符(多为乱码)。

解决方法很简单:
(1)要保证 [Results] 窗口中的中文字符能够正常显示,只需做如下设定:依次点击菜单
Edit?Preference?GeneralPreference? Results Colors?Colorscheme ,在下拉菜单中选择
“ Classic。

(2)要保证帮助文件能够以合适的字体显示,只需作如下设定即可:
依次点击菜单 Edit?Preference?GeneralPreference? Viewer Colors?Colorscheme ,在下拉菜单中
选择“Custom1 ”。

设定完成后点击“确定”。

Q4. 如何查看帮助文件的PDF 文件?
A:Stata12配备了完整的PDF 格式的使用手册,统一存放于“ D:\stata12\utilities”文件夹下。

你可以直接进入该文件夹查看相应的PDF 文件,亦可在 Stata 内部直接打开相应的
PDF 文件。

要打开完整的PDF 使用手册,依次点击菜单Help?PDFDocumentation即可:
若想查看特定命令的PDF 使用说明,可以先在命令窗口中输入该命令,如“helpregress”,浏览该帮助文件的最下方,点击下图中的[R]regress 即可打开regress的 PDF 帮助文件。

Q5. 如何使用Stata 官方提供的范例数据?
A:多数情况下,教程中提供的资料已经足够大家练习所需了。

当然,为了满足个别学员的需求,本教程还进一步提供了Stata 官方范例数据,统一存放于
D:\stata12\ado\Example文件夹中。

例如,你可以输入
use"D stata12\ado Exampl es\XTFi le abdata.dta", clear 命令导入范例数据 abdata.dta。

亦可点
击 Stata 主界面中的按钮(快捷键为 Ctrl+o ),到上述目录下选择你想要练习的数据文件。
