Hjorth Distribution


These functions provide information about the Hjorth distribution with location parameter equal to m, dispersion equal to s, and family parameter equal to f: density, cumulative distribution, quantiles, log hazard, and random generation.

The Hjorth distribution has density

f(y) = (1+s y)^(-f/s) exp(-(y/m)^2/2) (y/m^2+f/(1+s y))

where m is the location parameter of the distribution, s is the dispersion, and f is the family parameter.
