第八章多重共线性：解释变量相关会有什么后果

为什么不能容忍多重共线性？
• 一个模型中的某个变量违背常识。比如某些积极因素被“算”成了消极因素 • 模型应该儘量简捷
– 奥卡姆剃刀：如无必要，毋增实体
• 产生多重共线性的背景
– 经济变量之间具有共同变化趋势
• 哲学观点：事物是普遍联繫的。联繫的紧密程度有所不同。多重共线性会经常出现 • 如果一个回归方程之中，幾个自变量之间具有比较强的相关性，则自变量之间可以互相解释，我们可以只留下一个自变量： • 设y=x1+x2+c, 其中，x1=ax2, 则y=ax2+x2+c=(a+1)x2+c
• 这样阐述事物，越说越乱，与其说是“解释”，毋宁是“蛊惑”
生产函数的多重共线性
• 如果技術不变，劳动与资本投入会是等比例的。比如，每增加一部缝纫机，就要增加一个工人。此时，投入品之间是完全共线性，即等比例变化。
• 多途径投放广告，销售额的变动到底来自哪种广告形式，无法区分。各广告形式之间经常存在共线性。
如果存在 c1X1i+c2X2i+…+ckXki+vi=0
OLS估计量仍是最优线性无偏估计量
i=1,2,…,n
其中ci不全为0，vi为随机误差项
注意：
除非是完全共线性，多重共线性并不意味着任何基本假设的违背；因此，即使出现较高程度的多重共线性， OLS估计量仍具有线性性等良好的统计性质。问题在于，即使OLS法仍是最好的估计方法，它却不是“完美的”，尤其是在统计推断上无法给出真正有用的信息。
方差膨胀因子与b2、b3是线性关係，单调
递增，两个自变量之间的关係越密切，回归系数的变异程度就越大
没有一种检验方法能够彻底解决多重共线性问题。没有一个简单的方法解决这个多重共线性问题

AŒ 30, 2008Electrical noise and mitigation - Part 3: Shielding and grounding (cont filtering harmonicsThis excerpt from the book "Practical Grounding, Bonding, Shielding and Protection" concludes with a look at the shielded isolation transformer, ze reference grounds and signal transport ground planes, and the generation of in electrical systems and how they can be filtered.By G Vijayaraghavan, MarkBrown, Malcolm BarnesShielding and Surge Protection" by ordering fr and using offer code 92[Part 1begins by defining electrical noise, examreasons for its generation and looking at ways toits effects. Part 2looks at earth loop as a causethe ways in which noise can enter a signal cablcontrol, and shielding.]8.10 Shielded isolation transformerA shielded transformer is a two-winding transfusually delta"star connected and serves the fopurposes:∙Voltage transformation from the distribu voltage to the equipment's utilization voltage.∙Converting a 3-wire input power to a 4-wire output thereby deriving a stable neutral for the power supply wiring going to sensitive equ ∙Keeping third and its multiple harmonics away from sensitive equi allowing their free circulation in the delta winding.∙Softening of high-frequency noise from the input side by the natural i of the transformer, particularly true for higher frequency of noise the reactance becomes more as the frequency increases.∙Providing an electrostatic shield between the primary and the sec windings thus avoiding transfer of surge/impulse voltages passinginter-winding capacitance.Figure 8.27 shows the principle involved in a shielded transformer. The construction of the transformer is such that the magnetic core forms the innermost layer, followed by the secondary winding, the electrostatic shield made of a conducting material (usually copper) and finally the primary winding.Figure 8.27Principle of a shielded two winding transformerFigure 8.28 shows this detail.Figure 8.28Construction of a shielded two-winding transformerIt can be seen that the high-frequency surge is conducted to ground through the capacitance between the primary winding (on the left) and the shield, which is connected to ground. Besides the shield, the magnetic core, the neutral of the secondary winding and the grounding wire from the electronic equipment are all terminated to a ground bar, which in turn, is connected to the power supply ground/building ground. It is also important that the primary wiring to and secondary wiring from the isolation transformer are routed through separate trays/conduits. If this is not done, the inter-cable capacitances may come into play negating the very purpose of the transformer.Figure 8.29 shows the proper way for an isolation transformer to be wired. Note that the AC power supply wiring and the secondary wiring from the transformer are taken through separate conduits. Also, the common ground connection of the isolation transformer serves as the reference ground for the sensitive loads. The AC system ground electrode connection is taken through a separate metal conduit. If these methods are not followed and wiring/earth connections are done incorrectly, noise problems may persist in spite of the isolation transformer.Figure 8.29Wiring/earthing of a shielded two-winding transformer8.11 Avoidance of earth loopWe discussed earlier in this chapter about the earth loop being a primary mechanism of noise injection into sensitive signal circuits. One of the important noise mitigation measures is therefore the avoidance of ground loops altogether. We have also seen in the previous chapters that while keeping a separate ground for the sensitive equipment may resolve noise issues, it is an unsatisfactory solution from the safety point of view.The correct approach is therefore to keep a common electronic ground but bond it firmly with the power system ground at the source point. Figure 8.30 shows an installation with a ground loop problem.Figure 8.30Ground loop problemHere, the main computer system (bottom) and its user terminal are shown connected to the power circuit (including ground wiring) at two different points. A communication cable runs between the computer and its terminal. A ground loop is thus formed with the length of communication cable and the ground wire acting together in series.Figure 8.31 shows one way in which this loop can be tackled, by bringing the two power and ground connections together to outlets at a single point.Figure 8.31Solution to the ground loop problemThis arrangement may not be feasible or practical to adopt. What is really possibleis to introduce additional impedance in the ground loop so that the high-frequency noise prefers to take another low-impedance path and diverts itself away from the communication path. This is the principle behind the use of a longitudinal (or 'balun') transformer. Figure 8.32 demonstrates the action of this method.Figure 8.32Use of a 'balun' transformer for noise mitigation8.12 Use of insulated ground (IG) receptacleThe IG receptacles are used in situations where we wish to avoid the mixing of sensitive equipment ground and the building power system ground at all points except the power source (say, the secondary of the shielded isolation transformer) thus avoiding ground loops from forming. Figure 8.33 shows such a receptacle.Figure 8.33An exploded view of IG receptacleThe receptacle frame has a separate ground connection, which is bonded to the general ground system through the metallic conduit to ensure safe conditions. But the grounding wire from the sensitive equipment is an insulating wire, which runs through the conduit directly to the ground point of the source. Figure 8.34 illustrates such a connection.Figure 8.34Grounding while using an IG receptacle8.13 Zero signal reference grid and signal transport ground planeFrom the foregoing, it will be clear that correct ground connection is a key factor for error-free operation of sensitive equipment and elimination of ground loops to the best possible extent is of extreme importance.A practical way in which the above can be achieved is by using the support structures of the raised floor (which are common in computer installations and control rooms) as a ground grid called the zero signal reference grid (ZSRG). The grid is formed by the support structures of the raised floor usually arranged as 2 ft square tiles. Copper conductor of #4 AWG size is clamped to the structures forming a grid. All signal grounds of the sensitive equipment and enclosures of the equipment are connected to this grid by short grounding leads.The grid itself is connected to the power ground through more than one conductor. It is ideal to place the isolation transformer also on this grid and connect the secondary neutral point to the reference grid. Figure 8.35 shows the construction of a ZSRG installation.Figure 8.35Zero signal reference ground using a cavity floorWhen communication cables are used to interconnect two sensitive equipment, use of a signal transport ground plane (STGP) is recommended. This is a copper foil or a GI sheet on which the communication cable is placed so that it is shielded from electrostatic transfer of noise.Metallic cable trays on which a cable is placed and clamped close to it can also serve as an STGP. Within the same room the STGP can be bonded to the ZSRG at one or more points. When a cable runs between installations in different parts of a building, it will be necessary to have individual ZSRGs in each area and also ensure that the STGP is bonded at either end to these grids. In case balun transformers are also used on the signal cable, noise will be further reduced. Figure 8.36 shows such an installation.Figure 8.36Use of signal transport ground planeUse of ZSRG has an added bonus too. It provides numerous parallel grounding paths and thus avoids resonance situation. Resonance happens when the length of a ground lead coincides with quarter wavelength of the noise frequency (or 3/4, 1 1/4, etc.) causing the earth lead to act as an open circuit to these frequencies. With multiple ground paths, this is unlikely to happen.A judicious mix of ZSRG, shielded transformer and STGP used appropriately will go a long way in avoiding grounding related noise problems.Raised floor-supporting structure as a signal reference grid:∙Bolted down stringers (struts between supporting posts) assure low electrical resistance joints.∙Isolation from building steel except via computer system earthing conductors, conductor to computer systems central earthing point and to power source earth.∙Ideal floor height for crawling access is 30 in. less than 18 in. restricts airflow. For larger computer rooms, install firewall separation barriers to confine fire and Halon extinguishing gas.8.13.1 Self-resonance effect in grounding/bonding conductorsWhen dealing with grounding of power system conductors, we are concerned with the ground circuit resistance. But when dealing with circuits with high-frequency signals, it becomes necessary to consider the impedance of the grounding conductor. The grounding electrode conductors (the conductors that connect a system to the ground electrode) exhibit distributed capacitance and inductance in the length of the conductor. A particular conductor may resonate at a certain frequency (or it multiples) and may thus behave like an open-circuited conductor (refer Figure 8.37).Figure 8.37Impedance variation of a typical grounding electrode conductorIt is therefore advisable that grounding circuits of such systems be connected usingmultiple conductors with different lengths so that the combined grounding system does not resonate as a whole for any frequency. The ZSRG thus fulfills this need by providing multiple ground paths of differing lengths so that the ground path always has low impedance for any signal frequency (refer Figure 8.38).Figure 8.38Effective grounding by ZSRG8.14 Harmonics in electrical systemsThe subject of harmonics is not directly related to this course, except that it is also a contributory factor in electrical noise. It also causes several other problems in power circuit components such as motors, transformers and capacitor banks.A load that is purely resistive has the same wave shapes for voltage and current. Both are normally pure sinusoids. Most induction motors fed directly from AC mains also behave in a similar manner except that they draw some reactive load as well. The current waveform is still sinusoidal (see Figure 8.39).Figure 8.39Voltage and current waveforms of an induction motorHowever, the current waveform gets distorted when power electronic devices are introduced in the system to control the speed of motors. These devices chop off partLet us see how these shunt filters function. We can use acomputer to show what happens as harmonics are filtered froma distorted wave. The example chosen is a 120° square wavecurrent with a 10° commutation time; a typical line currentwaveform for a DC motor drive and for many AC drives.Here is the square wave before any filtering. The distortionfactor is 26% not too pretty a waveform (Figure 8.41a). Nowlet us take out the fifth harmonic.This may not look a whole lot better, but the distortionfactor is down from 26 to 18%, so things are improving(Figure 8.41b). Now let us take out the seventh as well.Things are actually looking better now. We can see the sinewave starting to emerge. Distortion factor is down to 11%(Figure 8.41c). Next, we take out the eleventh.Still no beauty queen, but the distortion factor is now only8% (Figure 8.41d). Let us add in the final element and removethe thirteenth harmonic.This is our final current waveform (Figure 8.41e). Thedistortion factor is 6%, so we are putting a reasonablecurrent into the utility. Of course, the significance ofthis current waveform to the voltage distortion would dependon the source impedance and the current level.Figure 8.41Reduction of harmonics by filtersHigher-frequency harmonics can be propagated by the powerconductors acting as antennae and appear as induced noisevoltages in nearby signal circuits.It is not possible to prevent harmonic currents altogether. But they can be prevented from flowing through the entire system by providing a separate low-impedance path for them. This is done by the use of adequately rated series tuned circuits consisting of a reactor and capacitor, which have equal impedance at a specific harmonic frequency.Several such tuned banks (one for each harmonic frequency) will be needed to totally divert all harmonics away from the system. However, for practical reasons, only a few of the lower order harmonics with larger magnitudes are filtered out, which is adequate to provide substantial reduction of harmonic content.Figure 8.41 shows how a filter might remove the high-frequency components and how the wave shape might appear as the removal takes place. A full treatment of this subject is beyond the scope of this book.8.15 SummaryIn this chapter, we have dealt with electrical noise in detail and the ways in which noise finds a path into sensitive signal circuits. We learnt the various methods by which noise can be reduced by avoiding shields, by separating the cabling, by using shielding transformers, by eliminating earth loops and by using zero signal reference grounds and signal transport ground planes. We also briefly dealt with the generation of harmonics and how they can be filtered.Printed with permission from Butterworth Heinemann。

2024英语人教版寒假作业与生活作业8年级

2024英语人教版寒假作业与生活作业8年级As the winter break approaches, students in grade 8 are faced with the task of completing their English homework and assignments. The 2024 English textbook, published by the People's Education Press, provides a comprehensive curriculum that challenges and engages students throughout the year. This year's winter homework and life assignment is no exception, offering a diverse range of activities and exercises that aim to reinforce language skills and encourage personal growth.The winter homework packet for grade 8 English focuses on several key areas, including reading comprehension, vocabulary development, grammar application, and written expression. One of the primary assignments is a literary analysis of a classic novel or short story. Students are required to read the selected work, analyze the characters, themes, and literary devices, and then compose a well-structured essay that demonstrates their critical thinking skills.In addition to the literary analysis, the winter homework also includes a series of vocabulary exercises. Students are provided with a list ofchallenging words and are expected to learn their definitions, parts of speech, and appropriate usage. These vocabulary activities not only expand students' lexical knowledge but also enhance their ability to communicate effectively in both oral and written contexts.Another component of the winter homework is a grammar review. The English textbook covers a range of grammatical concepts, from sentence structure to verb tenses and modifiers. The winter assignment includes a series of exercises that allow students to apply their understanding of these grammatical principles in various contexts, such as sentence correction, paragraph editing, and creative writing prompts.Beyond the academic focus of the winter homework, the 2024 English textbook also includes a "life assignment" component. This section encourages students to explore their personal interests, develop practical skills, and engage with their local community. One of the life assignment tasks is to create a personal journal or blog, where students can reflect on their experiences, set goals, and share their thoughts and feelings with others.Another life assignment involves a community service project. Students are asked to identify a local organization or cause that they are passionate about and then participate in a volunteer activity or fundraising initiative. This assignment not only promotes civicengagement but also fosters a sense of social responsibility and empathy among the students.The winter homework and life assignment also include opportunities for group work and collaboration. Students are encouraged to form study groups or peer-review teams to support each other's learning and development. These collaborative activities not only enhance students' communication and teamwork skills but also foster a sense of community and camaraderie within the classroom.Throughout the winter homework and life assignment, the 2024 English textbook emphasizes the importance of strategic learning and time management. Students are provided with guidance on effective study habits, organizational techniques, and goal-setting. These skills not only help students succeed in their academic pursuits but also prepare them for the challenges they will face in their future endeavors.One of the unique features of the 2024 English textbook is its integration of technology and digital resources. The winter homework and life assignment include opportunities for students to utilize online tools, such as language-learning apps, digital dictionaries, and collaborative platforms. By incorporating technology into the learning process, the textbook authors aim to engage students in a more dynamic and interactive way, while alsopreparing them for the increasingly digital world they will encounter.Overall, the 2024 English textbook's winter homework and life assignment for grade 8 represent a comprehensive and holistic approach to language learning and personal development. The assignments challenge students academically while also fostering their social, emotional, and practical skills. As students embark on this winter journey, they can expect to not only improve their English proficiency but also gain valuable insights and experiences that will serve them well in their future academic and personal pursuits.。
