  1. ➢ For explanatory variables having more than two categories, the overall significance is given by their corresponding P-values.
  2. ➢ The assessment made whether the required assumptions for the application of multiple logistic regression was fulfilled showed that this parsimonious model adequately fits the data as P = 0.287 (by using Hosmer and Lemeshow test).
