Both fixed effects (FE) and random effects (RE) meta-analysis models have been used widely in published meta-analyses. This article shows that FE models typically manifest a substantial Type I bias in significance tests for mean effect sizes and for moderator variables (interactions), while RE ...
Subject: Re:st: Re: fixed effects vs random effects Hi everybody. Kit Baum suggests an instrumental variable estimator to dela with endogeneity. But in this case what is the better estimator between IVfixed effect (xtivreg2, fe) and IV first-difference (xtivreg2, fd with, optionally, gmm...

I understand the basic differences between a fixed-effects and a random-effects model for a panel dataset, but what is the "between estimator"? The manual explains the command, but I cannot figure out what would lead one to choose (or not choose) the between estimator. ...
The main message is that not all analysis of variance models are fixed effects models and that random effects require different treatment from fixed effects. The entire discussion is illustrated by practical examples.doi:10.1080/00224065.1974.11980626Paul I. Feder...
