Specified by:

nullHypothesis in interface TestResult<Object>

Returns:

(undocumented)

pValue

public double pValue()

Description copied from interface: TestResult

The probability of obtaining a test statistic result at least as extreme as the one that was actually observed, assuming that the null hypothesis is true.

Specified by:

pValue in interface TestResult<Object>

Returns:

(undocumented)

statistic

public double statistic()

Description copied from interface: TestResult

Test statistic.

Specified by:

statistic in interface TestResult<Object>

Returns:

(undocumented)

toString

public String toString()

Description copied from interface: TestResult

String explaining the hypothesis test result. Specific classes implementing this trait should override this method to output test-specific information.
