Trait for hypothesis test results.

Method Summary
Modifier and TypeMethodDescriptionReturns the degree(s) of freedom of the hypothesis test.Null hypothesis of the test.double
pValue()
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.double
Test statistic.toString()
String explaining the hypothesis test result.

Method Details

degreesOfFreedom
DF degreesOfFreedom()Returns the degree(s) of freedom of the hypothesis test. Return type should be Number(e.g. Int, Double) or tuples of Numbers for toString compatibility. Returns:
 (undocumented)

nullHypothesis
String nullHypothesis()Null hypothesis of the test. Returns:
 (undocumented)

pValue
double pValue()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. Returns:
 (undocumented)

statistic
double statistic()Test statistic. Returns:
 (undocumented)

toString
String toString()String explaining the hypothesis test result. Specific classes implementing this trait should override this method to output testspecific information.
