The Stoppa distribution is a 3-parameter distribution that generalizes the
Pareto distribution, adding a second shape parameter but no location term.
The CDF is

                                    F(x) =  [1-(x/x0)-á]è    0 < x0 < x

Kleiber & Kotz (2003). *Statistical Size Distributions in Economics and
Actuarial Sciences.*    I do not believe that the Stoppa distribution has
been implemented in R under that name.


Does anyone know if the Stoppa distribution has been implimented in R under
a different name, or if there is a more generalized distribution containing
the Stoppa as a special case which has been implemented in R? (The
generalized beta of the second kind, maybe?) And if so, how you need to set
the parameters of the more general distribution to collapse it to the
Stoppa?

Any help anyone could offer would be greatly appreciated.
