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

定义

命名空间:

System.Windows.Forms.DataVisualization.Charting

程序集:

System.Windows.Forms.DataVisualization.dll

使用正态分布执行 Z 检验。

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

public System.Windows.Forms.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.Windows.Forms.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
