The data is supposedly Poisson distributed - expecting to see around 1000 incidences in any 10 minutes - but when I try to perform a goodness-of-fit test, I get a p-value of 0.0 --- Now sometimes you simply have to reject your null hypothesis, but I can't help but shake the feeling that I'm doing something wrong, as it's been a while since I had any training in … Use some statistical test for goodness of fit. This article discussed two practical examples from two different distributions. The p-value of the Log-Likelihood Ratio test is 0.03589 indicating that the model is doing better than the Intercept Only Model (a.k.a. 1. Goodness of Fit Test for normal and poisson distribution
