2024年9月5日 · Normally, everyone talks about the distribution of interarrival times in a Poisson Process are Exponential ... but what about the distribution of the actual event times?

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 at …

2015年5月25日 · The logic here seems obvious: The probability of a given wait time for independent events following a poisson process is determined by the exponential probability distribution $\lambda …

2025年4月22日 · As alluded to, this formula for P is found by composing the "nice" known solution for the Poisson kernel in the unit disk $\mathbb {D}$ through appropriate biholomorphisms so that it can …

2024年9月2日 · When would one use a negative binomial regression and when would one use Poisson regression with respect to the mean and variance?

2023年12月10日 · 1 I will give an intuitive explanation, only needing the defining properties of the Poisson Process and the exponential distribution, without needing any calculations involving …

2020年7月21日 · Poisson and quasi-Poisson will produce models with identical coefficients but different standard errors. The latter being adjusted for over or under dispersion. A negative binomial model …

2023年2月19日 · The Poisson and quasi-Poisson models differ in their assumptions about the form of the function relating the mean and variance of each observation. The Poisson assumes the variance …

Here is an example of application. Poisson regression is typically used to model count data. But, sometimes, it is more relevant to model rates instead of counts. This is relevant when, e.g., …

You can use poisson for non-integer data, as long as you use het-robust standard errors. This approach is fairly common in econometrics and statistics and goes under the name quasi-likelihood or quasi …
