Thank you very much for your answers. The problem is that the editor wants a formal test. So I guess that the Vuong test should be ok... 2011/3/24 Thomas Lumley tlum...@uw.edu On Thu, Mar 24, 2011 at 8:26 AM, Brian S Cade ca...@usgs.gov wrote: As a follow-up to Greg's suggested graphical

2011-03-23 Thread Boris New
Hi, I would like to compare two models in R with the same dependant variable but different predictors (two different types of frequency and reaction times as RT). An editor told me to have a look at Lorch and Myers 1990. Lorch and Myers use the following technique: 1) they perform regressions on
