Python kstest poisson

WebThe probability mass function for poisson is: f ( k) = exp. ⁡. ( − μ) μ k k! for k ≥ 0. poisson takes μ ≥ 0 as shape parameter. When μ = 0, the pmf method returns 1.0 at quantile k = 0. The probability mass function above is defined in the “standardized” form. To shift distribution use the loc parameter. WebIn statistics, the Kolmogorov–Smirnov test ( K–S test or KS test) is a nonparametric test of the equality of continuous (or discontinuous, see Section 2.2 ), one-dimensional probability distributions that can be used to compare a sample with a reference probability distribution (one-sample K–S test), or to compare two samples (two-sample ...
