WebOct 11, 2024 · It may be worth clarifying that in an ordered probit or logit model, you get one set of coefficients that represent the odds of a higher response to the question. However, when it comes to margins, you are inherently predicting the average probability of responding in each of the response categories (and you have 3 of them). Now, for … WebThe problem with this model is that the cutpoint function is deterministic, and codes are observed. But in pymc (and in other MCMC programs, e.g. JAGS), a deterministic node cannot also be observed. So this model can't be built directly in pymc.
