Dear all,
I'm using the ellipse package and I would like to verify if the
confidence region that I build with this package can be equivalent to  
an Union Intersection Test. I used different value for the t-statistic  
but I can not find the right equivalence.
Does someone know how to choose the right value?

Thanks a lot.
Antonio

You've posted this question several times now, with no reply that I've 
seen.  I think you need to be more specific.  As far as I know, 
"union-intersection" is a strategy for constructing a test, it's not a 
uniquely defined test.  So you should describe your union-intersection 
test, and then someone could help you to compare it to the confidence 
regions that ellipse computes.
