are.parglo.valid: Are the Distribution Parameters Consistent with the Generalized Logistic Distribution

Description

The distribution parameter object returned by functions of this package such as by parglo are consistent with the corresponding distribution, otherwise a list would not have been returned. However, other functions (cdfglo, quaglo, and lmomglo require consistent parameters to return the cumulative probability (nonexceedance), quantile, and L-moments of the distribution, respectively. These functions internally use the are.parglo.valid function. The FORTRAN source code of Hosking provides the basis for the function.

Usage

are.parglo.valid(para,nowarn=FALSE)

Arguments

para
A distribution parameter list returned by parglo.
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 a

Value

  • TRUEIf the parameters are glo consistent.
  • FALSEIf the parameters are not glo consistent.
