Suppose you are interested in explaining Student Evaluations of Teaching (which are calculated on the following 4-point scale: (1)Poor, (2)Fair, (3)Good,and (4)Excellent)in a sample of 15,239 college students and that using the multinomial logit you obtain the following coefficient estimates (standard errors in parentheses) $$\begin{array} { l l l lll } \widehat { S E T _ { i } } = &2.48 +& 0.97 \text { Avg. GPA } _ { i } - &1.52 \% \text { Freshmen } _ { i } - &0.24 \% \text { Male } _ { i } +& 2.04 \text { \% Majors } \\&( 0.83 ) &( 0.45 ) & ( 0.66 ) & ( 0.15 ) & ( 0.77 )\end{array}$$
a)How should you interpret the estimated coefficient on Average GPA? Does this make economic sense? Explain.
b)How should you interpret the estimated coefficient on % Freshmen? Does this make economic sense? Explain.
c)Do these estimates provide all of the information that you desire? If not,how can you obtain that information? Explain.
