# Distribution of Data

I have a question about glm model fitting of my data. The distribution shape is likely to follow a poisson distribution, but the response variable is not count/rate, but continuous decimals with both positive an negative values （as shown below).

Could you please give me some suggestions that which one should be more appropriate to my case?

• First fit an OLS model, then examine the residuals. In R you can get nice plots of the model by something like (pseudo code): m1 <- lm(DV~IV) plot(m1) – Peter Flom Feb 12 '14 at 15:34
