Repeat the analyses in Problem5.10 with continuation ratio models with logit, probit, and complementary log-log link functions.

 Problem5.10

Transcribed Image Text:

5.10 For the DOS data set, fit a cumulative logit model with the three-level depression diagnosis as the ordinal response and Age, Gender, CIRS, and MS as covariates. (a) Repeat the analyses (a), (b), and (c) in Problem 5.6. (b) Test whether the equal slopes assumption is true. (c) Based on the equal slope assumption, test the linear hypothesis: Ho: Age = 1 vs. Ha Age 1 and explain your results. Note that the above is not a linear contrast, and thus you may use an offset term.
