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

定義

命名空間:

System.Web.UI.DataVisualization.Charting

組件:

System.Web.DataVisualization.dll

Z 測試公式會使用常態分佈來執行 Z 測試。

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

參數

hypothesizedMeanDifference

Double

資料群組的假設平均差。

varianceFirstGroup

Double

第一個資料群組內的變異數。

varianceSecondGroup

Double

第二個資料群組內的變異數。

probability

Double

Alpha 值。 可接受的範圍介於 0 和 1 之間。

firstInputSeriesName

String

Series 物件的名稱，這個物件會儲存第一個群組的資料。

secondInputSeriesName

String

Series 物件的名稱，這個物件會儲存第二個群組的資料。

傳回

ZTestResult

ZTestResult 物件。

範例

下列程式碼示範如何使用此公式。

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");
