The goal: simulate chi square mixture distributions as a way of simulating likelihood ratio test statistics for some mixed models where the more specific model has some zero variance components (a la Pinheiro and Bates pg. 84-87)
The problem: R doesn't have the function ms which is apparently used by simulate.lme In the current version of nlme for R, is there a way around this? Is it possible to use the simulate function? Is this going to be rectified in the (eagerly anticipated) new release of nlme next month?
