[R-sig-ME] PCA-GLMM

[Saâd HANANE]

Hi,
I have performed a PCA analysis which highlighted two axes PC1 and PC2. I
want to perform a GLMM analysis considering the PC1 axis as a dependent
variable (variable to explain) with Poisson or negative binomial family,
but it was not possible since the values of this axis are negative. In such
a case what should I do?
I also need to perform glmmPQL to consider spatial autocorrelation. LME
could be a solution (instead of GLMM)? If yes, how could I perform glmmPQL?
Thank you for your precious help.
Regards.
