Dear everyone I'm dealing with a problem related to Poisson Ridge Regression. If anyone can help me in this regard by telling if any changes in the source code of "glm.fit" may help -- Regards Umesh Khatri
Probabaly not since you do not tell us what the problem is.

So is rseek.org where 'poisson ridge regression' gives lots of hits. If you click on 'functions' there is a link to the 'glmnet' package, which is a solid engine for penalized poisson regression.

You have not described the problem, provided sample data, or examples of output and error. So, right now all you have told anyone is that you have a problem. JWDougherty
---------- Forwarded message ---------- From: umesh khatri <khatriumesh88 at gmail.com> Date: Wed, 11 Jul 2012 16:15:11 +0530 Subject: Poisson ridge regression To: R-help at rproject.org I'm student of Masters in Statistics (Actuarial) from Central University of Rajasthan, India. I am doing a major project work as a part of the degree. My major project deals with fitting a glm model for the data of car insurance. I'm facing the problem of multicollinearity for this data which is visible by the plotting of data. But I'm not able to test it. In the case of linear models one can use VIF but what about count data. Another problem is as the multicollinearity is visible from the plot one solution is poisson ridge regression. But how to do the programming for this in R. I thought of making changes to "glm.fit" might help. But the codes are beyond my understanding. I'll be glad if someone can help me in this regard.
