I am trying to understand why the output from logistic regression of these two libraries gives different results. I am using the dataset from UCLA idre tutorial, predicting admit based on gre, gpa and rank. rank is treated as categorical variable, so it is first converted to dummy variable with rank_1 dropped. An intercept column is also added.
