Hi Bert:
I thought in centering Baci variable, but I wouldn`t like to draw a
conclusion based on the scaled response variable.
On the other hand, if I had to center the explanatory variable, that would
be great, but I cannot, as it is a factor.
Thanks a lot for your time. I really appreciated yo
Inline.

Ok. I`m trying to run a Poisson glmm with an observation-level random
intercept. But I`m getting the following error for the 'Baci' variable:
'Error: (maxstephalfit) PIRLS step-halvings failed to reduce deviance in
pwrssUpdate'. I guess this message is because the baci variable is not a
an intege
Can you explain why you need them as 'integer', A floating point
representation can hold a value upto ~4.5e15 as an "integer" keeping the
precision that you might need.

Please respond to the list. It will be obvious why in a second.
That's not my threshhold! -- it's R's. Your numeric integers cannot be
exactly represented as integers in R. Period. Maybe there are special
packages for extended arithmetic that can do this. but someone else
would have to help you th
That is the "impossible" case, since R integers are 32 bit signed (~2×10^9)
even in 64 bit R. You can Google for "R arbitrary precision" and look for
packages like Ryacas, bit64 or gmp. However, having such large integers stored
as integers would not be necessary for most statistical analyses so
No.

"Note that current implementations of R use 32-bit integers for
integer vectors, so the range of representable integers is restricted
to about +/-2*10^9: doubles can hold much larger integers exactly. "

Dear all:
I converted the columns (Baci, Meti, Fungii, Protozoai) into integers
(using excel) and then imported the data (.txt) into R. Interestingly, the
other three variables were loaded as INT, but the 'Baci' one continued as
Num.
I imported the data using the following command line:
X <- rea
