Please help with the following mathematical and statistical problems

1. Compare the ordinal regression model (ORM) with the continuation ratio model (CRM), and the adjacent category model.
2. compare the models such as the generalized ordered logit model (GOLM), the sequential model, the multinomial logit model (MNLM).
3. Evaluate the partial proportional odds model (PPOM), the partial continuation model (PCM), and the stereotype ordered regression model (SORM). Of all these models, which ones are the most useful?
