Open the Trust data-set

a. Run a multiple regression where expenditure on chicken (q5) is the dependent variable and the explanatory variables are: i. Price (price) ii. General attitude toward chicken (q9) iii. Perceived risk from chicken consumption (q27d) b. What is the goodness-of-fit? c. Estimate the model again and add the income variable (income) and the number of household components (q56). What is the goodness-of-fit now? Which goodness-of-fit indicator allows comparison between the two models? d. Estimate the regression equation again with the stepwise method. Which variables are kept in the model? e. Interpret the coefficients,relating unitary changes in the explanatory variables to changes in the dependent variables.
