vec2par {lmomco}R Documentation

Convert a Vector of Parameters to a Parameter Object of a Distribution

Description

This function converts the L-moments of the data to the parameters of a distribution. The type of distribution is specified in the argument list: cau, exp, gam, gev, glo, gno, gpa, gum, kap, nor, pe3, and wak.

Usage

vec2par(vec, type, nowarn=FALSE, ...)

Arguments

vec A vector of parameter values for the distribution specified by type.
type Three character distribution type (for example, type='gev').
nowarn A logical switch on warning surpression. If TRUE then options(warn=-1) is made and restored on return. This switch is to permit calls in which warnings are not desired as the user knows how to handle the returned value—say in an optimization algorithm.
... Additional arguments for the are.par.valid call that is made internally.

Value

An R list is returned.

type The type of distribution in three character format.
para The parameters of the distribution.
source Attribution specifying source of the parametes—“vec2par”.
