...*log(vr)+i*log(n1+ll$intercept)) with: ## number of observations - Intercept: n1<-ll$nn-ll$intercept ## fraction of sum of squared residulas model i ## and sum of squared residuals null model, I ## just can't understand why the vector ll$ress ## is subscripted double vr<-ll$ress[i,j]/ll$nullrss ## maximum number of variables i ^^ This seems to match the calculation done by extractAIC but it doesn't! Maybe anyone can tell me about the reason of the variation of the BIC-values? Best regards, Jan Henckens ### Minimal Example: require(leaps) bridge <- read.table("http://ww...

Any idea on how one could coax an R-squared out of biglm? Thanks in advance for any help with this!
