Constructor Detail

Statistic

public Statistic(double chiSquare,
                 double degreesOfFreedom)

Creates a new instance of chiSquare

Parameters:

chiSquare - Chi-square value

degreesOfFreedom - Number of degrees of freedom in the test

Method Detail

getChiSquare

public double getChiSquare()

Gets for chiSquare

Returns:

Chi-square value

getDegreesOfFreedom

public double getDegreesOfFreedom()

Getter for degreesOfFreedom

Returns:

Number of degrees of freedom

getTestStatistic

public double getTestStatistic()

Description copied from interface: ConfidenceStatistic

Gets the statistic from which we compute the null-hypothesis probability. In an ANOVA, this would be the "F" statistic. In a t-test, this would be the "t" value. And so forth.

Returns:

Confidence statistic used to compute the null-hypothesis probability.
