Cumulative Distribution Function of the Wakeby Distribution

Description

This function computes the cumulative probability or nonexceedance probability of the Wakeby distribution given parameters (xi, α, β, gamma, and delta) of the distribution computed by parwak. The cumulative distribution function of the distribution has no explicit form.

Usage

cdfwak(x, wakpara)

Arguments

x A real value.
wakpara The parameters from parwak or similar.

Value

Nonexceedance probability (F) for x.
