Method Detail

getFitness

public double getFitness(double value,
                         double target,
                         double factor)

XXX

Specified by:

getFitness in interface FitnessFunction

Parameters:

value - the variate value

target - the ideal value of the variate (typically the mean value for a normal distribution).

factor - a shape factor for the distribution (typically the standard deviation for a normal distribution).

Returns:

the probability density function for the variate value value given a continuous distribution with ideal value: target and shape factor: factor.
