Method Details

cdf

public double cdf(double x,
 Parameter p)
           throws IncorrectDistributionParameterException

Description copied from interface: Distribution

This method is used to obtain from the distribution its cumulative distribution function evaluated where required by the user.

Specified by:

cdf in interface Distribution

Parameters:

x - the x value

p - the p value

Returns:

always 0 because in this type of distribution it has no sense to request the cdf of the distribution.

Throws:

IncorrectDistributionParameterException - if the operation cannot be completed

pdf

public double pdf(double x,
 Parameter p)
           throws IncorrectDistributionParameterException

Description copied from interface: Distribution

This method is used to obtain from the distribution its probability distribution function evaluated where required by the user.

Specified by:

pdf in interface Distribution

Parameters:

x - the x value

p - the p value

Returns:

always 0 because in this type of distribution it has no sense to request the pdf of the distribution.

Throws:

IncorrectDistributionParameterException - if the operation cannot be completed

theorMean

public double theorMean(Parameter p)
                 throws IncorrectDistributionParameterException

This method is used to obtain from the distribution the value of its own theoretic mean.

Specified by:

theorMean in interface Distribution

Parameters:

p - parameter of the constant distribution.

Returns:

double with the theoretic mean of the distribution.

Throws:

IncorrectDistributionParameterException

theorVariance

public double theorVariance(Parameter p)
                     throws IncorrectDistributionParameterException

Description copied from interface: Distribution

This method is used to obtain from the distribution the value of its own theoretic variance.

Specified by:

theorVariance in interface Distribution

Parameters:

p - the p value

Returns:

always 0 because in this type of distribution it has no sense to request the variance of the distribution.

Throws:

IncorrectDistributionParameterException - if the operation cannot be completed

nextRand

public double nextRand(Parameter p)
                throws IncorrectDistributionParameterException

This method is used to obtain from the distribution the next number distributed according to the distribution parameter.

Specified by:

nextRand in interface Distribution

Parameters:

p - parameter of the exponential distribution.

Returns:

double with the next random number of this distribution.

Throws:

IncorrectDistributionParameterException
