public abstract class AbstractQuantityStatisticPredicate<S>
extends ScalarSupport<S>
implements BinaryPredicate<QuantifiedValue<S>>, java.io.Serializable

Base class for quantity conditions based on statistical tests. This class provides utility methods to implementations for doing calculations and statistics based on the values (mean) and the errors of quantities.

Method Detail

inverseGaussianCumulativeDistributionFunction

protected S inverseGaussianCumulativeDistributionFunction(S value)

Evaluate the inverse Gaussian Cumulative Distribution Function and return the result as an element of the backing field. This method uses Cheating for the time being.

Parameters:

value -

Returns:

subtractQuantities

protected QuantifiedValue<S> subtractQuantities(QuantifiedValue<S> left,
                                                QuantifiedValue<S> right)

Calculates the difference of two quantities (including error propagation)

Parameters:

left - left operand

right - right operand

Returns:

the difference as a quantity

zTestValueForDifference

protected S zTestValueForDifference(QuantifiedValue<S> left,
                                    QuantifiedValue<S> right)

Calculate the z-test z value for the difference of the two values (number of sigmas the difference of the mean values is away from zero)

Parameters:

left - the left operand

right - the right operand

Returns:

the z value
