cdfwak {lmomco}

Cumulative Distribution Function of the Wakeby Distribution

Description

This function computes the cumulative probability or nonexceedance probability of the Wakeby distribution given parameters (\xi, \alpha, \beta, \gamma, and \delta) computed by parwak. The cumulative distribution function has no explicit form, but the pdfwak (density) and quawak (quantiles) do.

Usage

cdfwak(x, para)

Arguments

x

A real value vector.

para

The parameters from parwak or vec2par.

Value

Nonexceedance probability (F) for x.
