Dear R-helpers,
I recently switched from SAS to R, in order to model the occurrence of
rare events through logistic regression.
Is there a package available in R to calculate the Goodman-Kruskal
Gamma?
After searching a bit I found a function "rcorr.cens" which should do
the job, but it is not clear to me how to define the input vectors? Is
"x" a vector with the fitted probabilities and "s" a vector containing
the observed response variable? Or does anybody know an alternative?
Any help would be greatly appreciated,
Thanks,
Tom
