Talk:Poisson regression

Regularized Poisson regression
There is not a lot of literature on this, but I can't find anyting taht calls it "Regularized Poisson regression" although that seems a better name that Poisson Ridge Regression. Are there other names that are more popular?Billlion (talk) 11:28, 27 February 2019 (UTC)

Rating
I gave this a "Start-Class" rating on the quality scale. To improve in quality, this article needs at least the following: This is a good topic, and it deserves a thorough treatment. —Aetheling (talk) 05:45, 26 June 2010 (UTC)
 * 1) A picture showing the conditional Poisson distribution as x changes.
 * 2) A separate section on maximum likelihood estimation, giving the likelihood function with graphs of its surface, and going into greater detail on numerical methods for finding its maximum.
 * 3) Discussion of the relationship to proportional hazard models.
 * 4) A section on the use of Poisson regression in spatial models.
 * 5) A section giving more examples in detail.
 * 6) Better and deeper references.

Ridge regularization
The present article states: "Regularization can be added to this optimization problem by instead maximizing


 * $$\sum_{i=1}^m \log(p(y_i;e^{\theta' x})) + \lambda ||\theta||^2$$,"

But maximizing and a positive sign on the penalty term seem not to go hand in hand. Shouldn't it be a minus instead? &mdash; fnielsen (talk) 13:37, 6 April 2011 (UTC)

Yes, I believe you are correct. I've changed it. -BlueScreenD — Preceding unsigned comment added by BlueScreenD (talk • contribs) 03:51, 16 May 2012 (UTC)
