Talk:Fixed effects estimation

From Wikipedia, the free encyclopedia

Fixed effects model should be merged into this article, and the seemingly opposite descriptions on that page should either be harmonized or deleted if they simply represent an error. Torfason 14:39, 18 April 2007 (UTC)

The article doesn't seem to be correct when it says "A random effects model makes the additional assumption that the individual effects are randomly distributed. It is thus not the opposite of a fixed effects model, but a special case." My understanding and what I have read elsewhere is that the random effects model is more general than the fixed effects model. Setting the variance of the effect to zero derandomizes the random effects and makes them fixed effects. I didn't change the article yet because I'm not familiar with the formalisms of this area yet.
