Hi,
I'm trying to perform a glm model on count data (poisson distribution of
the errors) where data are nested.
glmmodel-glm(y~x/z,poisson)
x and z are factors, z nested within x, y is count data.
In that point the R just stuck and not respond anymore. I tried
glmmodel-glm(y~x,poisson)
and there were no problems. Trying
glmmodel-glm(y~x/z)
gave the same no response. Similar problem with continuous data (normal
distribution of the errors).
I am using R 2.3.1 on Windows XP
Thanks
Yuval
Please see the signature and provide commented, minimal,
self-contained, reproducible code. Namely, what is 'x' and 'z'? My
guess is ~x/z produces so large a model matrix you are approaching your
limits of memory. But, there's no way to tell without more information.
HTH,
