ikr.simlib.distributions.continuous

Class ConstantDistribution

java.lang.Object

ikr.simlib.distributions.Distribution

ikr.simlib.distributions.continuous.ContinuousDistribution

ikr.simlib.distributions.continuous.ConstantDistribution

All Implemented Interfaces:

ReflectionConstructable, ReflectionConstructable3<SimNode,Parameters,RandomNumberGenerator>

public class ConstantDistribution
extends ContinuousDistribution

Deterministic Value

Meaning:	A constant value \(d\) is returned
Parameters:	constant ("mean") value \(d\)
PDF:	\(P(T=t) = f(t) = \delta(t-d) \)
DF:	\(P(T \le t) = F(t) = \sigma(t-d) = \begin{cases} 0 &\mbox{for } t < d \\ 1 & \mbox{else } \end{cases} \)
Expected value:	\(E[T]= d \)
Variance:	\(VAR[T]= 0\)
Coefficient of variation:	\(c_T= 0\)
LST:	\(\phi(s) = exp(-sd)\)
Parser example:	[...].Distribution = Constant [...].Distribution.Mean = 1.7
