Specified by:

makeRandom in interface SpecificityTest<Template>

Parameters:

comps - the number of model components to use

Returns:

returns the generated Template

calculateError

public double calculateError(Template tem1,
                             Template tem2)

Calculates the error between two Templates

Specified by:
