[R] Lmer, heteroscedasticity and permutation

2006-10-16 Thread Alan Juilland
it in spite of hard heteroscedasticity ? 4/ A last question concerning SAS. My model appears to not converge in SAS, indicating a structure in the variance. Is it implying something in lmer or lme ? Many Thanks -- Alan Juilland -- Alan Juilland – PhD Student Department of Ecology and Evolution
