cdfkur {lmomco}

Cumulative Distribution Function of the Kumaraswamy Distribution

Description

This function computes the cumulative probability or nonexceedance probability of the Kumaraswamy distribution given parameters (\alpha and \beta) computed by parkur. The cumulative distribution function is

F(x) = 1 - (1-x^\alpha)^\beta \mbox{,}

where F(x) is the nonexceedance probability for quantile x, \alpha is a shape parameter, and \beta is a shape parameter.

Usage

cdfkur(x, para)

Arguments

x

A real value vector.

para

The parameters from parkur or vec2par.

Value

Nonexceedance probability (F) for x.
