Hi,
I am trying to extract the coefficients matrix from a gls summary.
Contrary to the lm function, the command fit$coefficients returns
only the estimates of the model, not the whole matrix including the
std errors, the t and the p values.
example:
ctl <- c(4.17,5.58,5.18,6.11,4.50,4.61,5.17,4.53,5.33,5.14)
trt <- c(4.81,4.17,4.41,3.59,5.87,3.83,6.03,4.89,4.32,4.69)
group <- gl(2,10,20, labels=c("Ctl","Trt"))
weight <- c(ctl, trt)
fitlm<-lm(weight~group)
summary(fitlm)$coefficients ### returns estimates, std errors, t
values and Pr(>|t|)
fitgls<-gls(weight~group)
summary(fitgls)$coefficients ### returns only the estimates.
I would like to be able to extract the whole coefficient matrix form
the gls. Any ideas how I could do that ?
Thanks for the help,
