BACKGROUND

●The report below is about the food sales , I instance the

resident population (10 000 ) , per capita income the

first year , meat sales , egg sales , the fish sales .

●In order to build mathematical models to understand the

relationship of each variable and its food sales , and I

take statistics of Tianjin from 1994 to 2007 the demand

for food

Y represents the model of food sales ( tons / year)，X1 said the resident population (10 000 ) , The X2 per capita income the first year , X3：meat sales , X4：said egg sales , X5：said the fish sales .

0.0777 means when resident population increase 1 point, the other factors remain unchanged, the food sales increase 0.777 point .

0.1190 means when resident population increase 1 point, the other factors remain unchanged, the food sales increase 0.1190 point .

2.6677 means when resident population increase 1 point, the other factors remain unchanged, the food sales increase
