I'm fitting a regression model for censored data with three categorical
predictors, say A, B, C. My final model based on the survreg function is
Surv(..) ~ A*(B+C).
I know the three-way group mean estimates can be computed using the predict
function. But is there any way to obtain two-way group mean estimates, say
estimated group mean for (A1, B1)-group? The sample group means don't
incorporate censoring and thus may not be appropriate here.
