probability - Distribution of Event Times in a Poisson Process ...
Sep 5, 2024 · 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?
Why is Poisson regression used for count data?
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 …
How to choose between poisson and binomial distributions
The Poisson distribution is easier to work with than the binomial distribution. It is easier to compute the pdf and especially the cdf. Its generating functions have nice properties. Etc. …
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 …
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 …
Why Specifically Use Poisson Regression For Count Data?
Sep 8, 2022 · Why should Poisson Regression be used for Count Data instead of a "vanilla linear regression"? I understand the basic argument : Count Data is by definition discrete and you …
What is the correct inter-arrival time distribution in a Poisson …

Deriving Newton’s gravitational potential through Poisson’s …
Nov 30, 2023 · 0 I am trying to derive Newton’s gravitational potential $\phi_N = -\frac {GM} {r}$ from Poisson’s equation $\Delta \phi_N = 4\pi G\rho$, where G is the gravitational constant, M …
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 …
Invert Poisson distribution to get x based on probability
Nov 11, 2022 · The Poisson distribution function is given by: f(x) = P(X=x) = (e^(-λ) * λx )/x! I am writing some code and need to determine the number of events that will happen in a time step. …
