Plotting predictions from an ordinal regression using the plot_predictions() function

[llewmills]

Thank you for the information, that makes sense that, given it being an ordinal model, the graphs make those odd-looking stepped jumps from one integer level to the next. Your last point I definitely can speak to: as long as you are using the same data and those data are integers, you can compare a gaussian version of the model to an ordinal. It’s also worth noting that when the data are bounded counts, you can also compare gaussian to binomial models.
