cdfwak: Cumulative Distribution Function of the Wakeby Distribution

Description Usage Arguments Value Author(s) References See Also Examples

Description

This function computes the cumulative probability or nonexceedance probability of the Wakeby distribution given parameters (ξ, α, β, γ, and δ) computed by parwak. The cumulative distribution function has no explicit form, but the pdfwak (density) and quawak (quantiles) do.

Usage

1
cdfwak(x, para)

Arguments

x

A real value vector.

para

The parameters from parwak or vec2par.

Value

Nonexceedance probability (F) for x.
