  1. 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 at …

  2. r - Rule of thumb for deciding between Poisson and negative binomal ...

    Nov 6, 2023 · The Poisson distribution implies so a one-sample test can provide a -value for testing Poisson vs. negative binomial. Another test for equidispersion is the Lagrange Multiplier which …

  3. Finding the probability of time between two events for a poisson process

    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 $\lambda …

  4. 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 equal 1, but …

  5. Distribution of the time for the first ocurrence in a Poisson Process ...

    Jul 2, 2023 · 0 Time of the first arrival in Poisson process with rate $\lambda$ is exponential random variable $\sim Exp (\lambda)$.

  6. Autocorrelation function for a Compound Poisson Process?

    Feb 3, 2025 · Now I construct a compound Poisson process in the following way. Let $X_1$ be the waiting time for the $1$ -th event (of the same Poisson process defined before).

  7. Standard errors when implementing the 'Poisson Trick' (estimating ...

    Jul 3, 2025 · Standard errors when implementing the 'Poisson Trick' (estimating multinomial from two poisson regressions) Ask Question Asked 7 months ago Modified 7 months ago

  8. Probability Poisson distribution - Mathematics Stack Exchange

    The number of cars appearing in a car park follows a Poisson distribution with a mean of 10 cars per hour. Find the probability of there being: (a) Exactly 5 cars in a 30 minute interval, (b) At most 3 cars …

  9. How to interpret coefficients in a Poisson regression?

    This was in discussions of interpreting logistic regression coefficients, but Poisson regression is similar if you use an offset of time at risk to get rates. You add first all the coefficients (including the intercept …

  10. Quasi Poisson vs Negative Binomial [duplicate] - Cross Validated

    Jul 21, 2020 · 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 …
