lmomco (version 2.2.5)

are.par.valid: Are the Distribution Parameters Consistent with the Distribution

Description

This function is a dispatcher on top of the are.parCCC.valid functions, where CCC represents the distribution type: aep4, cau, emu, exp, gam, gep, gev, glo, gno, gov, gpa, gum, kap, kmu, kur, lap, ln3, nor, pe3, ray, revgum, rice, sla, st3, texp, tri, wak, or wei. For lmomco functionality, are.par.valid is called only by vec2par in the process of converting a vector into a proper distribution parameter object.

Usage

are.par.valid(para, paracheck=TRUE, ...)

Arguments

para

A distribution parameter object having at least attributes type and para.

paracheck

A logical controlling whether the parameters are checked for validity and if paracheck=TRUE then effectively this whole function becomes turned off.

...

Additional arguments for the are.parCCC.valid call that is made internally.

Examples

vec  <- c(12,120)           # parameters of exponential distribution
para <- vec2par(vec,'exp')  # build exponential distribution parameter
                            # object
# The following two conditionals are equivalent as are.parexp.valid()
# is called within are.par.valid().
if(are.par.valid(para))    Q <- quaexp(0.5,para)
if(are.parexp.valid(para)) Q <- quaexp(0.5,para)
