When I looked into this some time ago, then I thought of adding the similar function that uses the scipy distribution ppf for the quantiles. IIRC there are the tables with the values for some standard distributions, that I matched. (I didn't look at medcouple.)

In this case it would be easier to compare the absolute kurtosis with the value for the t distribution for example. (I don't remember if it made sense when the distribution parameters need to be estimated.)

One application I have seen somewhere is robust jarque-bera for normal distribution.
