Ok, I've pretty much figured this out. My problem was that I didn't restrict the sample to those in the relevant group before estimating the model. When I do that I get the results I expected. Sorry to bother you... PS From: gretl-users-bounces(a)lists.wfu.edu

[Gretl-users] Multiple Imputation analysis

2010-03-05 Thread Nathan Paxton
Hi all, I've recently discovered gretl, having been a fairly elementary user of R and Stata for a few years. I do work with multiple imputation datasets, and I generate them in R, using the Amelia package. But the sorts of tests I want to run aren't easily done using an

[Gretl-users] weird bootstrap behavior

2010-03-05 Thread Summers , Peter
Folks, I've just noticed some very strange behavior when I try to generate studentized bootstrap confidence intervals in a model with only a constant (this is problem 5.6 in Davidson/MacKinnon's ETM). The model is earnings data regressed on a dummy variable for a particular income group, so it'
