Dear all,
I have a large data set and would like to fit a logistic regression
model using the bigglm function. I need to include an offset in the
model but when I do this the bigglm function seems to ignore it.
For example, running the two models below produces the same model and
the offset is ignored
bigglm(y~x,offset=z,data=Test,family=binomial(link = "logit"))
bigglm(y~x,data=Test,family=binomial(link = "logit"))
Is it possible to fit an offset using bigglm? And if so, what am I doing
wrong?
Thanks,
Richard
