Method Detail

cumulative

public abstract double cumulative(double[] adblX)
                           throws java.lang.Exception

Compute the Cumulative under the Distribution to the given Variaate Array

Parameters:

adblX - Variate Array to which the Cumulative is to be computed

Returns:

The Cumulative

Throws:

java.lang.Exception - Thrown if the inputs are invalid

incremental

public abstract double incremental(double[] adblXLeft,
                                   double[] adblXRight)
                            throws java.lang.Exception

Compute the Incremental under the Distribution between the 2 Variate Arrays

Parameters:

adblXLeft - Left Variate Array to which the Cumulative is to be computed

adblXRight - Right Variate Array to which the Cumulative is to be computed

Returns:

The Incremental

Throws:

java.lang.Exception - Thrown if the inputs are invalid

density

public abstract double density(double[] adblX)
                        throws java.lang.Exception

Compute the Density under the Distribution at the given Variate Array

Parameters:

adblX - Variate Array at which the Density needs to be computed

Returns:

The Density

Throws:

java.lang.Exception - Thrown if the input is invalid
