 

  Hi,

 

  I'm trying to perform a power simulation for a simple multilevel
model, using the function glmmPQL in R version 2.8.1.  I want to extract
the p-value for the fixed-effects portion of the regression, but I'm
having trouble doing that.  I can extract the coefficients
(summary(fit)$coeff), and the covariance matrix (summary(fit)$varFix),
but I can't grab the p-value (or the t-statistic.)  Could someone
explain how to do this?

 

  Please send responses to halper@health.nyc.gov.

 

  Thanks in advance,

 

  Howard
