Dear collegues,

Is there anyone who ever used qqmath().

Actually, I want to know the distribution of the dependent varible.
It's a count number, so it should be poisson or negative binomial
distribution.
But how could I use R to get the  ë and á? Or to demonstrate the
distribution to be negative binomial ?

I tried my best to find the examples by google, but failed.

Thank you for the suggestions.

Best!
