If you choose any feasible combination of skewness and kurtosis, you can find a member of the Johnson system that has that same skewness and kurtosis. The SB distribution is a family that models bounded distributions.

NettetJohnson Unbounded distribution Format: JohnsonU ( a1, a2, b, g) The main use of the Johnson Unbounded distribution is that it can be made to have any combination of skewness and kurtosis. Thus, it provides a flexible distribution to fit to data by matching these moments. That said, it is an infrequently used distribution in risk analysis.
