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!
