is denoted by continuous probability distribution Pareto type-IV probability distribution Alejandra Gonzalez-Beltran Orlaith Burke Philippe Rocca-Serra The Pareto(IV) distribution is a continous probability distribution which is described with a cumulative distribution function of the following form: F(y) = 1 − [1 + ((y − a)/b)1/g]−s for y > a, b > 0, g > 0 and s > 0. a is the location parameter, b is the scale parameter, g is the inequality parameter s is the shape parameter The distribution is used in actuarial science, economics, finance and telecommunications, but not restricted to those fields. dparetoIV(x, location = 0, scale = 1, inequality = 1, shape = 1, log = FALSE) https://cran.r-project.org/web/packages/VGAM/VGAM.pdf https://cran.r-project.org/web/packages/VGAM/VGAM.pdf page 517 probability distribution scale parameter ready for release
