Class DiscreteConstantDistribution

java.lang.Object

ikr.simlib.distributions.Distribution

ikr.simlib.distributions.discrete.DiscreteDistribution

ikr.simlib.distributions.discrete.DiscreteConstantDistribution

All Implemented Interfaces:

ReflectionConstructable, ReflectionConstructable3<SimNode,Parameters,RandomNumberGenerator>

public class DiscreteConstantDistribution
extends DiscreteDistribution

Discrete Deterministic Value

Meaning:	A constant integer value \(d\) is returned
Parameters:	constant integer (mean) value \(d\)
Distribution:	\(P(X=i) = \begin{cases} 1 &\mbox{for } i=d \\ 0 & \mbox{else } \end{cases} \)
Expected value:	\(E[X]=d\)
Variance:	\(VAR[X]=0\)
Coefficient of variation:	\(c_X=0\)
Generating func.:	\(G(z)=z^d \)
Parser example:	[...].Distribution = DiscreteConstant [...].Distribution.Data = 5
