QUESTION
A normal distribution has a kurtosis of 3. With an increase in outliers in the distribution, the tails become "fat" and the kurtosis increases beyond 3.
How do I generate a random distribution between two numbers with kurtosis greater than 3 (preferably around 5-7)?

Answered 2020-Jan-14 at 17:14Since kurtosis is not one of the parameters of the normal distribution function, you have to use another method that generates a function that approximates the normal distribution. It gets complicated. Have a look at this: https://stats.stackexchange.com/questions/43482/transformation-to-increase-kurtosis-and-skewness-of-normal-r-v
The link above gives examples using R (sigh) code, but I think it is straightforward enough to allow you to code the equivalent in Python. This is one of several expansions (i.e. layering of functions) that I am aware of that allow you to achieve this.
Unfortunately, no easy solution that I am aware of.
