StatisticFormula.ZTest(Double, Double, Double, Double, String, String) 方法

定义

命名空间:

System.Web.UI.DataVisualization.Charting

程序集:

System.Web.DataVisualization.dll

Z 检验公式使用正态分布执行 Z 检验。

public:
 System::Web::UI::DataVisualization::Charting::ZTestResult ^ ZTest(double hypothesizedMeanDifference, double varianceFirstGroup, double varianceSecondGroup, double probability, System::String ^ firstInputSeriesName, System::String ^ secondInputSeriesName);

public System.Web.UI.DataVisualization.Charting.ZTestResult ZTest (double hypothesizedMeanDifference, double varianceFirstGroup, double varianceSecondGroup, double probability, string firstInputSeriesName, string secondInputSeriesName);

member this.ZTest : double * double * double * double * string * string -> System.Web.UI.DataVisualization.Charting.ZTestResult

Public Function ZTest (hypothesizedMeanDifference As Double, varianceFirstGroup As Double, varianceSecondGroup As Double, probability As Double, firstInputSeriesName As String, secondInputSeriesName As String) As ZTestResult

参数

hypothesizedMeanDifference

Double

各数据组的平均值之间的假设差值。

varianceFirstGroup

Double

第一组数据的方差。

varianceSecondGroup

Double

第二组数据的方差。

probability

Double

Alpha 值。 可接受的范围为 0 到 1。

firstInputSeriesName

String

Series 对象的名称，该对象存储第一个组的数据。

secondInputSeriesName

String

Series 对象的名称，该对象存储第二个组的数据。

返回

ZTestResult

ZTestResult 对象。

示例

以下代码演示如何使用此公式。

Dim result As ZTestResult = Chart1.DataManipulator.Statistics.ZTest(0.2, 2.5, 4.5, 0.05, "Series1", "Series2")  

ZTestResult result = Chart1.DataManipulator.Statistics.ZTest(0.2, 2.5, 4.5, 0.05, "Series1", "Series2");
