Number of obs. = 160, LR χ²(18) = 33.64, Prob > χ² = 0.0139, Pseudo R2 = 0.1916. ***p < 0.01, **p < 0.05, *p < 0.1. The partial proportional odds model retained the proportional odds constraint for all covariates based on variable-specific tests in gologit2, pl, resulting in identical estimates across the two cumulative logits. LR: likelihood ratio.
