May be worth following up on r-sig-mixed-models . My guess would be that if you're willing to treat your data set as 'large' (e.g. your guess is that the 'residual degrees of freedom', whatever that may mean, are > 40 ), then you could go ahead and use the naive translation from Z-score to p-value; otherwise it probably devolves to the usual 'effective residual degrees of freedom for complex multilevel/ smoothing models' can of worms. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
