Constructor Detail

ContDistWeibull

public ContDistWeibull(Model owner,
                       java.lang.String name,
                       double mean,
                       double beta,
                       boolean showInReport,
                       boolean showInTrace)

Constructs a simple Weibull-distributed pseudo random generator with the given values as mean and beta of the distribution. Only positive values are allowed.

Parameters:

owner - Model : The distribution's owner

name - java.lang.String : The distribution's name

mean - double : The mean value for this distribution

beta - double : The beat value for this distribution

showInReport - boolean : Flag for producing reports

showInTrace - boolean : Flag for producing trace output

Method Detail

getBeta

public double getBeta()

Returns the beta value of the Weibull distribution.

Returns:

double : the mean value of the Weibull distribution

sample

public java.lang.Double sample()

Returns the next pseudo random number of the Weibull distribution.

Overrides:

sample in class ContDistExponential

Returns:

Double : The next negative exponential pseudo random number

getInverseOfCumulativeProbabilityFunction

public java.lang.Double getInverseOfCumulativeProbabilityFunction(double p)

Abstract method to map a double p from 0...1 to the distribution's domain by determining the value x that satisfies P(X < x) = p.

Overrides:

getInverseOfCumulativeProbabilityFunction in class ContDistExponential

Parameters:

p - double: A value between 0 and 1

Returns:

N : The value x that satisfies P(X < x) = p
