Hello.

I am a graduate student using GLIMMIX to analyze count data.  I am
investigating the effects that the point count distance to industrial
disturbance has on bird abundance.  Several of my models are bringing
up a note which I have not encountered before.  Has anyone encountered
this warning?  Any advice?  I would appreciate any advice.

Thanks,

Holly

Out of curiosity, why didn't you set use the adaptive quadrature
method (method=3Dquad)? -Ryan
