TwoSampleZTest Class

Represents a test that the difference between two proportions of independent samples is significant.

Definition

Namespace: Numerics.NET.Statistics.Tests
Assembly: Numerics.NET (in Numerics.NET.dll) Version: 9.0.2
C#
public sealed class TwoSampleZTest : HypothesisTest
Inheritance
Object  →  HypothesisTest  →  TwoSampleZTest

Remarks

Use the TwoSampleZTest class to test the hypothesis that the difference between proportions of independent samples is significant.

Constructors

TwoSampleZTest() Constructs a new unpaired TwoSampleZTest for the specified samples.
TwoSampleZTest(Int32, Double, Int32, Double, Double, HypothesisType) Constructs a new TwoSampleZTest for the specified samples.

Properties

Count1 Gets or sets the number of observations of the first sample.
Count2 Gets or sets the number of observations of the second sample.
Difference Gets or sets the proposed difference between the two means.
Distribution Gets the probability distribution used in the hypothesis test.
(Inherited from HypothesisTest)
HypothesisType Gets or sets whether the test is one or two-tailed.
(Inherited from HypothesisTest)
Name Gets the name of the hypothesis test.
(Overrides HypothesisTest.Name)
Proportion1 Gets or sets the proportion for the first sample.
Proportion2 Gets or sets the proportion for the second sample.
PValue Gets the probability that the test statistic would take on the calculated value under the alternate hypothesis.
(Inherited from HypothesisTest)
SignificanceLevel Gets the significance level used to test the null hypothesis.
(Inherited from HypothesisTest)
Statistic Gets the value of the test statistic.
