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 …
How does Poisson thinning work? - Mathematics Stack Exchange
Oct 19, 2024 · The Poisson process on $\mathbb {R}$ is called non-homogenous with rate $\lambda (t)$ if its intensity measure has density $\lambda (t)$ (total mass of which might not …
Why is Poisson regression used for count data? - Cross Validated
Oct 4, 2013 · 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 …
r - Rule of thumb for deciding between Poisson and negative …
Nov 6, 2023 · The Poisson distribution implies so a one-sample test can provide a P -value for testing Poisson vs. negative binomial. Another test for equidispersion is the Lagrange …
Finding the probability of time between two events for a poisson …
May 25, 2015 · 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 …
An intuitive explanation of the Poisson equation?
Dec 8, 2023 · Poisson Equation: The Poisson equation, $$\nabla^2 u = f$$, describes how a scalar function (u) changes in response to a given "influence" represented by (f). It's like …
Poisson or quasi poisson in a regression with count data and ...
I have count data (demand/offer analysis with counting number of customers, depending on - possibly - many factors). I tried a linear regression with normal errors, but my QQ-plot is not …
spss - Difference between binomial, negative binomial and Poisson ...
I am looking for some information about the difference between binomial, negative binomial and Poisson regression and for which situations are these regression best fitted.
How to Choose Poisson Time Interval - Cross Validated
Oct 23, 2020 · A Poisson process is one where mean = var = λ. How do you decide what time interval fulfills these criteria when fitting the Poisson distribution to a process? Can all …
Checking if two Poisson samples have the same mean
This is an elementary question, but I wasn't able to find the answer. I have two measurements: n1 events in time t1 and n2 events in time t2, both produced (say) by Poisson processes with …
