Special Modeling IssuesIn the output shown above, the variable male has the value of 1 for malesand 0 for females and the variable black has the value of 1 for blacks and0 for non-blacks. The variable age94 has the value of 0 for age 16, 1 forage 17, up to 7 for age 23. An interpretation of the logistic regressioncoefficient for class 1 is that comparing class 1 to class 4, the log oddsdecreases by -.285 for a unit increase in age, is 2.578 higher for malesthan for females, and is .158 higher for blacks than for non-blacks. Thisimplies that the odds ratio for being in class 1 versus class 4 whencomparing males to females is 13.17 (exp 2.578), holding the other twocovariates constant.Following is a plot of the estimated probabilities in each of the fourclasses where age is plotted on the x-axis and the other covariates takeon the value of one. This plot was created and exported as an EMF fileusing the PLOT command in conjunction with the Mplus postprocessinggraphics module.Class 1, 12.7%Class 2, 20.5%0.6Class 3, 30.7%Class 4, 36.2%0.40.2001234567Probabilityage94PARAMETERIZATION OF MODELS WITH MORE THANONE CATEGORICAL LATENT VARIABLEThe parameterization of models with more than one categorical latentvariables is described in this section.
