meanCompound {Compounding} | R Documentation |
Function meanCompound calculates mean value of the random variable X.
meanCompound(parent,compound,compoundDist,params,...)
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. |
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
