DF, degrees of freedom; LRT, likelihood ratio test; DR, deviance reduction; Pr, probability of χ2 value exceeding the deviance reduction; , reference group. Variables are added into the model in order of presentation in table. Unexplained variations after fitting the model. Estimates are from the model with all independent variables added. Standard error of the estimate. Exponentiating the estimates.
