Is there a means by which the variance within latent classes can be assessed relative to the variance between classes in GMM (via MPlus output or otherwise)?

There is not a specific part in the output that gives this, but you can compute the between-class variance as a function of the model-estimated parameters. You get the estimated mean in each class from which you can compute the overall estimated mean as a weighed sum of class-specific means using class probabilities as weights. Then compute the sums of squares of the difference between the class-specific and overall means. These computations can be done by hand or in Model Constraint using New parameters.
