UniformDistribution

public UniformDistribution(double minX,
                           double maxX)

Method Detail

probability

public double probability(double X)

Description copied from class: ProbabilityDistribution

Probability density function.

Specified by:

probability in class ProbabilityDistribution

Returns:

the probability that a stochastic variable x has the value X, i.e. P(x=X).

cumulative

public double cumulative(double X)

Description copied from class: ProbabilityDistribution

Cumulative distribution function.

Specified by:

cumulative in class ProbabilityDistribution

Returns:

the probability that a stochastic variable x is less then X, i.e. P(x<X).

inverse

public double inverse(double probability)

Description copied from class: ProbabilityDistribution

Inverse of the cumulative distribution function.

Specified by:

inverse in class ProbabilityDistribution

Returns:

the value X for which P(x<X).
