Why is Poisson regression used for count data?
Poisson distributed data is intrinsically integer-valued, which makes sense for count data. Ordinary Least Squares (OLS, which you call "linear regression") assumes that true values are …
probability - Distribution of Event Times in a Poisson Process ...
Sep 5, 2024 · I am trying to learn how to prove the following: if we know k k events occurred in a Poisson process between times t1 t 1 and t2 t 2, the exact times of these events are uniformly …

Sep 18, 2019 · This is because the CDF of Poisson distribution is related to that of a Gamma distribution. Hence the incomplete gamma function.
Relationship between poisson and exponential distribution
Note, that a poisson distribution does not automatically imply an exponential pdf for waiting times between events. This only accounts for situations in which you know that a poisson process is …
Poisson regression with large samples: is it wrong to change the …
Due to the factorial in a Poisson distribution, it becomes impractical to estimate Poisson models (for example, using maximum likelihood) when there are many observations. So, for example, …
