- * For variables having more than two categories, the overall significance is given by their corresponding P – values N.B. The combined contribution of the rest 12 variables was very minimal (LRT = 19.67, (df = 20), P > > 0.20). This justifies the dropping of these variables so as to have a more parsimonious model that works just as the full model.
