PoissonIntegerRVRV
Constructor.- Parameters:
lambdaRV
- a random variable that determines the parameter λ which gives the mean of the distribution for a Poisson random variable
-
PoissonIntegerRVRV
Constructor with a mode to allow tables to be allocated.- Parameters:
lambdaRV
- a random variable that determines the parameter λ which gives the mean of the distribution for a Poisson random variablemode
- true if tables should be allocated to improve execution speed when a PoissonIntegerRV is created; false otherwise- See Also:

doNext
Description copied from class:RandomVariableRVN
Get the next value for a random variable. In general, each value will be independent of the last.- Specified by:
doNext
in classRandomVariableRVN<Integer,
PoissonIntegerRV> - Returns:
- the next random variable
- Throws:
RandomVariableException
- the next random variable could not be generated.
