Method Detail

oneWay

public SensitivityFunctionOneWay oneWay(Evidence evidence,
                                        State hypothesis,
                                        ParameterReference parameter)

Calculates how a hypothesis varies based on changes to a single parameter.

Parameters:

evidence - The evidence.

hypothesis - The state whose probability is to be analysed, based on changes to a single parameter.

parameter - The single parameter that can be varied.

Returns:

The sensitivity function.

twoWay

public SensitivityFunctionTwoWay twoWay(Evidence evidence,
                                        State hypothesis,
                                        ParameterReference parameter1,
                                        ParameterReference parameter2)

Calculates how a hypothesis varies based on changes to two parameters.

Parameters:

evidence - The evidence.

hypothesis - The state whose probability is to be analysed, based on changes to a single parameter.

parameter1 - The first parameter that can be varied.

parameter2 - The first parameter that can be varied.

Returns:
