I would appreciate your reflection on the following. I need a quantitative figure to evaluate weather the covariate varies across second level units in the process of simulation. Of course I will be running thousands of them and would need to program the condition in code. In one of the

Dear listers, I can't find the variance or se of the coefficients in a multilevel model using lme. The component of an lme() object called apVar provides the estimated asymptotic covariance matrix of a particular transformation of the variance components. Dr. Bates

Dear listers, I can't find the variance or se of the coefficients in a multilevel model using lme. I want to calculate a Chi square test statistics for the variability of the coefficients across levels. I have a simple 2-level problem, where I want to check weather a certain covariate varies

of lme, the plot(intervals) can be used to assess variability rather than the chi-square in HLM. -Original Message- From: Andrej Kveder [mailto:[EMAIL PROTECTED] Sent: Wed 6/25/2003 5:24 PM To: R-Help Cc: Subject: [R] within group
