  1. 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 …

  2. 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 …

  3. probability - Cumulative Distribution function of a Poisson ...

    Sep 18, 2019 · This is because the CDF of Poisson distribution is related to that of a Gamma distribution. Hence the incomplete gamma function.

  4. 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 …

  5. 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, …

  6. Distribution of distance from origin to any point of Poisson point …

    Jan 3, 2022 · In distance distribution in Poisson point process, a similar distance distribution was calculated but it was assumed that the number of points are known. With this assumption we …

  7. 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 …

  8. Expectation Poisson Distribution - Mathematics Stack Exchange

    The number of major snowstorms per year that shut down business is assumed to have a Poisson distribution with mean 1.5. What is the expected amount paid to the company under this policy …

  9. Moment Generating Function of Poisson - Mathematics Stack …

    Moment Generating Function of Poisson Ask Question Asked 11 years, 3 months ago Modified 5 years, 10 months ago

  10. Confusion regarding Poisson distribution conditioned on uniform ...

    Dec 16, 2018 · From SOA Sample #307: The number of workplace accidents occurring in a factory on any given day is Poisson distributed with mean $λ$ . The parameter $λ$ is a …
