Evaluating the Fit of a Logit Model

a) SAS/Stata Tasks.

i) Create a dummy variable to indicate females (as you did in Chapter 7 ).

ii) Create a dummy variable to indicate whether the respondent is overweight

(coded 1 if bmiR is at or above 25 and 0 if bmiR is below 25).

iii) Use proc logistic in SAS and logit in Stata to regress the overweight dummy on the female dummy. Call this Regression #1.
