This is basically a statistics question, despite the fact that you refer to an R implementation. You should therefore probably post on a statistics list, like stats.stackexchange.com, especially the part about asking for alternative R^2. -- Bert On Wed, Nov 7, 2012 at 9:01 AM, Marion Jacquot wro

[R] pseudo R-squared with likfit (geoR)

2012-11-07 Thread Marion Jacquot
We want to compute a pseudo R-squared for a model whose parameter estimation was based on maximum likelihood (function likfit, package geoR). I tried to compute the R2 proposed by Maddala (1983) which compare the maximized likelihood for the model without any predictor and the maximized likeliho
