Web24 Sep 2024 · You can use the ztest () function from the statsmodels package to perform one sample and two sample z-tests in Python. This function uses the following basic syntax: statsmodels.stats.weightstats.ztest(x1, x2=None, value=0) where: x1: values for the first sample x2: values for the second sample (if performing a two sample z-test) WebThe discrete module contains classes for count distributions that are based on discretizing a continuous distribution, and specific count distributions that are not available in scipy.distributions like generalized poisson and zero-inflated count models. The latter are mainly in support of the corresponding models in statsmodels.discrete.
