validParameter-methods: Methods for function validParameter in Package `distrMod'

Description

Methods for function validParameter in package distrMod to check whether a new parameter (e.g. "proposed" by an optimization) is valid.

Usage

validParameter(object, ...)
# S4 method for ParamFamily
validParameter(object, param)
# S4 method for L2ScaleUnion
validParameter(object, param, tol=.Machine$double.eps)
# S4 method for L2ScaleFamily
validParameter(object, param, tol=.Machine$double.eps)
# S4 method for L2LocationFamily
validParameter(object, param)
# S4 method for L2LocationScaleFamily
validParameter(object, param, tol=.Machine$double.eps)
# S4 method for BinomFamily
validParameter(object, param, tol=.Machine$double.eps)
# S4 method for PoisFamily
validParameter(object, param, tol=.Machine$double.eps)
# S4 method for L2ScaleShapeUnion
validParameter(object, param, tol=.Machine$double.eps)

Value

logical of length 1 --- valid or not

Arguments

object

an object of class ParamFamily

param

either a numeric vector or an object of class ParamFamParameter

tol

accuracy upto which the conditions have to be fulfilled

...

additional argument(s) for methods.

Details

method for signature

ParamFamily

checks if all parameters are finite by is.finite if their length is between 1 and the joint length of main and nuisance parameter of object, and finally, if a call to modifyParam(object) with argument param would throw an error.

L2ScaleUnion

checks if the parameter is finite by is.finite, and if it is strictly larger than 0 (upto argument tol).

L2ScaleFamily

checks if the parameter length is 1, and otherwise uses L2ScaleUnion-method.

L2LocationFamily

checks if the parameter is finite by is.finite, if its length is 1

L2LocationScaleFamily

checks if the parameter length is 1 or 2 (e.g. if one features as nuisance parameter), and also uses L2ScaleUnion-method.

BinomFamily

checks if the parameter is finite by is.finite, if its length is 1, and if it is strictly larger than 0 and strictly smaller than 1 (upto argument tol)

PoisFamily

checks if the parameter is finite by is.finite, if its length is 1, and if it is strictly larger than 0 (upto argument tol)

L2ScaleShapeUnion

uses L2ScaleUnion-method, checks if parameter length is 1 or 2 (e.g. if one features as nuisance parameter), and if shape is strictly larger than 0 (upto argument tol)

Examples

 NS <- NormLocationScaleFamily()
 validParameter(NS, c(scale=0.1, loc=2))
 validParameter(NS, c(scale=-0.1, loc=2))
 validParameter(NS, c(scale=0, loc=2))
 validParameter(NS, c(mean=2, sd=2))
