Problem #1: Annual Income WebbIn SAS, a proportional odds model analysis can be performed using proc logistic with the option link = clogit. Here clogit stands for cumulative logit. In this example, we are going to use only categorical predictors, white (1=white 0=not white) and male (1=male 0=female), and we will focus more on the interpretation of the regression coefficients. selina shen facebook
