pseudo R-squared with likfit (geoR)
...compare the
maximized likelihood for the model without any predictor and the
maximized likelihood for the model with all predictors.
I got a really low value (0,01%). Did I miss something? Are there other
R-squared which are more appropriate than the R2 of Maddala? :
>sp05_l01 <- likfit(cnm05g, *ini.cov.pars=vm05*, lik.method = "REML",
trend = trend.spatial(~ logIKA04 + nbLitre0 +
nbLitre1, cnm05g))#complete model
>sp05_nt <- update(sp05_01, trend = trend.spatial("cte", cnm05g))
#null model
>1-(sp07_nt$loglik/sp07_l0$loglik)^(2/590)#...
