The kurtosis is a measure of the “tailedness” of a distribution (not its “peakedness”, contrary to interpretations offered by various sources). Skewness measures an imbalance between tails. A distribution with high kurtosis, by contrast, has a propensity to produce more outliers in either tail; it is tail-weighted relative to . Given this knowledge, we can now define a function for plotting any kind of distribution. The important bit is to be careful about the parameters of the corresponding scipy.stats function (Some distributions require more than a mean and a standard deviation). You can check those parameters on the official docs for scipy.stats.. The exponential distribution:Beta-Binomial Distribution¶. The beta-binomial distribution is a binomial distribution with a probability of success p that follows a beta distribution.
