Helping a colleague with a brms-specified ordinal regression model and I’m a little confused by the terminology. For ordinal regression, I’m most familiar with the `ordered_logistic`

/`ordered_probit`

specification with parameters for the latent mean and cutpoints. In brms I see generated stancode is using the cumulative_logit_lpmf/cumulative_probit_lpmf and intercepts of some sort. Is intercept simply another name for cutpoints?

This is a useful paper: OSF which says

Note that there is no intercept in the predictor term, because the thresholds

τk replace the model’s intercept as both are not identified at the same time.

Ok, so in the terminology of that paper, `ordered_logistic`

with cutpoints is the same as a cumulative model with thresholds, yes?

Yes. See also my ordinal tutorial paper.
