The gnlr3 function (in Jim Lindsey's GNLM package) fits this distribution in this form:

f(y) = fy^(f-1)/((m/s)^(fs) Gamma(s)) y^(f(s-1)) exp(-(y s/m)^f)

*(1)
*

I would like to include a fourth parameter, say u, like this:

f(y) = fy^(f-1)/((m/s)^(fs) Gamma(s)) (y-u)^(f(s-1)) exp(-((y-u) s/m)^f)

*(2)
*

Any suggestions for a better approach?
