Note. The χ2 indicates the difference between the −2 log likelihoods of the full model and the model is this independent variable was omitted. Exp(B) indicates that the odds ratio of being in the class as opposed to the reference category as a function of a one-unit increase of the independent variable. Means are reported for all variables save for sex, and married, which are expressed in percentages.
