Demo of Skew Lognormal Cascade Distribution: Have fun playing!
If you don't know where to start, try η = 0.5, β = -0.3, g = 0.1.
That is approximately the parameters for the US stock market.
The tail gets fatter rapidly when η > 0.5.

The drop at the very last bit of the right tail is
due to lack of data beyond the range. It does NOT reflect
the real tail behavior.
