Format: VoseDagum(a, b, p, U)
The Dagum distribution is often encountered in the actuarial literature or the income distribution literature.
The distribution was originally derived by Dagum, when he investigated the income elasticity of the cdf of income.
a and p are shape parameters and b is a scale parameter.
The Dagum distribution has sometimes been used for fitting to aggregate fire losses.
The Dagum distribution is also called the Inverse Burr distribution or the Kappa distribution. When a = p, the distribution is also called the Inverse Paralogistic distribution.
VoseDagum generates values from this distribution or calculates a percentile
VoseDagumObject constructs a distribution object for this distribution
VoseDagumProb returns the probability density or cumulative distribution function for this distribution
VoseDagumProb10 returns the log10 of the probability density or cumulative distribution function
VoseDagumFit generates values from this distribution fitted to data, or calculates a percentile from the fitted distribution
VoseDagumFitObject constructs a distribution object of this distribution fitted to data
VoseDagumFitP returns the parameters of this distribution fitted to data
