Method Detail

cumulative

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

Compute the Cumulative under the Distribution to the given Variate Array/Variate Combination

Parameters:

adblX - R^d The Variate Array to which the Cumulative is to be computed

dblY - R^1 The Variate to which the Cumulative is to be computed

Returns:

The Cumulative under the Distribution to the given Variate Array/Variate Combination

Throws:

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

incremental

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

Compute the Incremental under the Distribution between the Variate Array/Variate Pair

Parameters:

dblYLeft - Left R^1 Variate from which the Cumulative is to be computed

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

dblYRight - Right R^1 Variate to which the Cumulative is to be computed

Returns:

The Incremental under the Distribution between the Variate Array/Variate Pair

Throws:

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

density

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

Compute the Density under the Distribution at the given Variate Array/Variate

Parameters:

adblX - R^d The Variate Array to which the Cumulative is to be computed
