bigglm() results different from glm()
Dear all,
I am using the bigglm package to fit a few GLM's to a large dataset (3
million rows, 6 columns). While trying to fit a Poisson GLM I noticed
that the coefficient estimates were very different from what I obtained
when estimating the model on a smaller dataset using glm(), I wrote a
very basic toy example to compare the results of bigglm() against a
glm() call. Consider the
