WebYou can use poisson regression with a continuous Y variable because poisson regression provides consistent estimators as long as E ( Y i X i) = e x p ( X i β) --- an amazing, useful, and much-overlooked fact. However, you can't do this for binary Y in general. The reason is the same reason you can't use OLS for binary Y in general. WebIn Poisson statistics, the mean and variance of the distribution are equal to the number of positive events. The standard deviation is the square root of the variance. So, if you have 2 events in a region the CV of that data is roughly 71%, whereas with 100 events, the CV drops to about 10%. But, what does this really mean? enertia microsystems inc

WebMar 3, 2024 · The Poisson distribution is a probability distribution that is used to model the probability that a certain number of events occur during a fixed time interval when the events are known to occur independently and with a constant mean rate.
