Public Shared Function PairedTTest (

	Optional difference As Double = 0,
	Optional type As HypothesisType = HypothesisType.TwoTailed
) As TwoSampleTTest

C++/CLI

public:
static TwoSampleTTest^ PairedTTest(
	Vector<double>^ sample1, 
	Vector<double>^ sample2, 
	double difference = 0, 
	HypothesisType type = HypothesisType::TwoTailed

static member PairedTTest : 
        sample1 : Vector<float> * 
        sample2 : Vector<float> * 
        ?difference : float * 
        ?type : HypothesisType 
(* Defaults:
        let _difference = defaultArg difference 0
        let _type = defaultArg type HypothesisType.TwoTailed
*)
-> TwoSampleTTest

Parameters

sample1 Vector<Double>: A vector containing a sample from the first population.
sample2 Vector<Double>: A vector containing a sample from the second population.
difference Double (Optional): The proposed difference between the population means. The default is 0.
type HypothesisType (Optional): A HypothesisType value that specifies whether the test is two-tailed (the default) or one-tailed.

Return Value

TwoSampleTTest
A paired two sample t test for the specified samples.

Exceptions

ArgumentNullException

sample1 is null.

-or-

sample2 is null.

DimensionMismatchException

sample1 and sample2 do not have the same length.

InsufficientDataException

The length of the samples is less than 2.
