The reason i use glmnet is that it makes the handling of 400,000 observations easier to handle in terms of memory, I am looking on sparse matrices but i dont understand how to build interacting using sparse matrices On Tue, Oct 25, 2011 at 12:34 PM, Marc Schwartz wrote: > > On Oct 25, 2011, at

If I understand you correctly, it sounds like you need to do some reading. ?lm and ?formula tell you how to specify linear models for glm or glmnet. However, if you do not have sufficient statistical background, It probably will be incomprehensible, in which case you should consult your local stat

We are workin on building a logistic regression using 1. We are doing a logistic regression with binary outcome variable using a set of predictors that include 8 continuous and 8 category predictors 2. We are trying to implement interaction between two variables (continuous and category or just c
