Method Summary

Modifier and Type	Method	Description
double	getPValue()	Returns the test statistic p-value.
double	getStatistic()	Returns the test statistic.
default boolean	reject(double alpha)	Returns true iff the null hypothesis can be rejected with 100 * (1 - alpha) percent confidence.

Method Details

getStatistic

double getStatistic()

Returns the test statistic.

Returns:

the statistic

getPValue

double getPValue()

Returns the test statistic p-value.

The number returned is the smallest significance level at which one can reject the null hypothesis.

Returns:

the p-value

reject

default boolean reject(double alpha)

Returns true iff the null hypothesis can be rejected with 100 * (1 - alpha) percent confidence.

The default implementation uses p < alpha.

Parameters:

alpha - Significance level of the test.

Returns:

true iff null hypothesis can be rejected with confidence 1 - alpha

Throws:

IllegalArgumentException - if alpha is not in the range (0, 0.5].
