This preview shows page 10 - 15 out of 24 pages.

9.) You have estimated a multiple regression model with 6 explanatory variables and an intercept from asample with 46 observations. What is tcif you want to perform a right-tailed hypothesis test at the .01 level of significance? 10.) You estimate a model with 5 explanatory variables and an intercept from a data set with 247 observations. To test hypotheses on this model you should use a t distribution with how many degrees of freedom? 11. A model estimated using a dataset with 125 observations generates the following results.VariableβStd. ErrortP>|t|x2-0.012640.005519-2.28937x30.5957920.01448241.13934

How can you estimate non-linear function forms using least squares? 17.) If you have the following economic modely = β1+ β2x - β3x2What is dy/dx? x 17. You have the following economic modely = β1+ β2x + β3If β2is positive and β3is negative what is the general shape of F(x)? x 2 18. What is an interaction term?
