WebThe ordinal Package I The ordinal package provides two main functions: 1. clm for cumulative link models (including ordered logit and probit). 2. clmm for mixed CLMs – same thing but with random slopes and intercepts. I CLMs are more flexible than ordered logit and probit because they allow you to specify some effects as nominal. 35 / 38
