Hi Sammy, Thanks for the response, that was actually another question i had (what is the appropriate test to evaluate (pearson chi sq vs scaled pearson X2)..assuming your correct and i should look at the pearson the value i have is 1.27 is that considered close enough to 1 to assume there is no overdispersion ?

--thanks, nevin
