VB One Way Anova Example

Imports CenterSpace.NMath.Core


Namespace CenterSpace.NMath.Examples.VisualBasic

  A .NET example in Visual Basic showing one-way analysis of variance (anova).
  Public Class Form1
    Inherits System.Windows.Forms.Form

#Region " Windows Form Designer generated code "

    Public Sub New()
      MyBase.New()

      This call is required by the Windows Form Designer.
      InitializeComponent()

      Add any initialization after the InitializeComponent() call

      Create the data to analyze. Class OneWayAnova will accept data in
      several formats. The one below uses an array of DoubleVectors. Each
      vector in the array contains the data for a group.
      Dim Table(4) As DoubleVector

      Table(0) = New DoubleVector("[24 15 21 27 33 23]")
      Table(1) = New DoubleVector("[14 7 12 17 14 16]")
      Table(2) = New DoubleVector("[11 9 7 13 12 18]")
      Table(3) = New DoubleVector("[7 7 4 7 12 18]")
      Table(4) = New DoubleVector("[19 24 19 15 10 20]")

      Create the one-way ANOVA
      Dim Owa As OneWayAnova = New OneWayAnova(Table)

      The AnovaTable property is a DataFrame instance that contains
      a traditional ANOVA table. Use the ToDataTable() method of
      the DataFrame to create a ADO DataTable.
      Dim DT As DataTable = Owa.AnovaTable.ToDataTable()

      Set the grids DataSource property to the DataTable just created.
      DataGrid1.DataSource = DT

    End Sub

    Form overrides dispose to clean up the component list.
    Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
      If disposing Then
        If Not (components Is Nothing) Then
          components.Dispose()
        End If
      End If
      MyBase.Dispose(disposing)
    End Sub
