hCompound: function hCompound

In Compounding: Computing Continuous Distributions

Description

Function hCompound calculates value of the hazard rate function of the random variable X.

Usage

hCompound(x,parent,compound,compoundDist,params,...)

Arguments

x	vector of quantiles
parent	name of the parent distribution. It can be any continuous distribution supported by R.
compound	name of the compound distribution. It can be any discrete distribution supported by this package.
compoundDist	list of available compounding distributions
params	Parameter or list of parameters of compounding distribution.
...	Parameters of continuous distribution could be provided as additional parameters.

Details

Parameters of the parent distribution must be provided in the same way as it is in built in R functions. See http://127.0.0.1:23174/library/stats/html/Distributions.html
