Hi,
I am trying to use the sgrender function with Proc Princomp to develop a scatter plot of observations with TWO ellipses. I basically have two populations that seem to be distinct, but I would like to establish an individual 95% confidence interval ellipse over each population. I am completely stumped on how to do it and the closest I have come is to use the template for a score plot on principal components. Any suggestions?
Thanks in advance - Brian
