Interface AbcDistance

All Known Implementing Classes:

AbcAbsDistance

public interface AbcDistance

Create the distance measure required for the ABC rejection algorithm.

Method Summary

Modifier and Type	Method and Description
double	calculate(AbcNamedQuantity generated, AbcNamedQuantity observed) Calculated the distance between the observed data and the generated data.

Method Detail

calculate

double calculate(AbcNamedQuantity generated,
                 AbcNamedQuantity observed)

Calculated the distance between the observed data and the generated data. Depending on the project, the implementing class can create summary statistics from the data.

Parameters:

generated - the data generated from the mdoel.

observed - the observed data.

Returns:

a measure of the calculated distance between the observed and generated data, for example, if we have a simple case where the data is single value the distance returned may be the absolute value of the difference in data.
