# hCompound: function hCompound In Compounding: Computing Continuous Distributions

## Description

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

## Usage

 `1` ```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
