Heterogeneous Longitudinal Residuals #50

Closed AdamMS closed 1 year ago

AdamMS commented 1 year ago

Does JMBayes2 accommodate heterogeneous residual variance in the longitudinal model? -- e.g. residuals are larger for men than for women. I am implementing this in nlme::lme() as follows:

weights = varIdent(form = ~ 1 | Sex)

If JMBayes2 does accommodate them, where do I find the posterior estimates of the group-specific variance terms in the model output?

Thank you

This is currently not possible.

Thank you for the information.
