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: exp, gam, gev, glo, gno, gpa, gum, kap, kur, ln3, nor, pe3, ray, revgum, rice, wak, or wei. Internally, this function is called only by vec2par in the process of converting a vector into a proper distribution parameter object for this package.

Usage

are.par.valid(para,...)

Arguments

para

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

...

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

Value

• TRUE
  If the parameters are consistent with the distribution specified by the type attribute of the parameter object.
• FALSE
  If the parameters are not consistent with the distribution specified by the type attribute of the parameter object.

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.parexp.valid(para)) Q <- quaexp(0.5,para)
