The table includes the parameter estimates for the variables retained in the multivariate regressions after the stepwise selection. For continuous variables, the parameter estimate corresponds to the change in the score for a change of 1 unity of the explanatory variable, all other things being equal; for categorical variables, it corresponds to the difference in score for the associate category compared to the reference category, all other things being equal.
