Method Details

testIndependence

public boolean testIndependence(Collection<Double> samples)

Description copied from interface: IIndependenceTest

Tests, whether the sequence of samples appears to be independent.

Specified by:

testIndependence in interface IIndependenceTest

Parameters:

samples - the sequence of samples.

Returns:

true, if the samples appears to be independent; false else.

getLowerSampleLimit

public int getLowerSampleLimit()

Description copied from interface: IIndependenceTest

Returns the minimal number of samples necessary for a proper test result. Avoid testing sequences smaller than the lower limit.

Specified by:

getLowerSampleLimit in interface IIndependenceTest

Returns:

the minimal number of samples necessary for a proper test result.
