Hello,
Thank You for response.Yes,It is discrete data.I have tried discrete model
using goodfit() test.But that too is not working.Is there any other test for
discrete data?
When I try goodfit() test for discrete distribution:
gf<-goodfit(x[[1]],type= "nbinomial",method= "MinChisq")
where x[[1]]

You are telling us a) the response is discrete and b) there is a
substantial probability that the value is zero. The gamma distributon
is a model for a continuous response, your response is integer valued.
Perhaps you should consider something the Poisson or Negati
Dear R users;
Is there any function to plot the confidence ellipse (Hotelling's T^2)
in an score plot from a PCA?
I have the scores off course , say scores for PC1 and PC2, and the

Thanks for any hint

a quick look at it shows you would be trying to access y[n+1] in the
last part of that loop and that is greater than the number of entries
in 'y' so you will get an NA and this is not legal for comparisons.

bx[i] = T

The point is don't use cbind -- use data.frame.

That won't work. The data arg to plot (and most other functions that
