Cumulative link models A cumulative link model is a model for ordinal-scale observations, i.e., observations that fall in an ordered finite set of categories. Ordinal observations can be represented by a random variable Yi that takes a value j if the ith ordinal observations falls in the j’th category where j = 1,...,J and J ≥ 2.3A ...
