probability
The probability for which the t-value is required. Allowable range is 0-1.
Probability
degreeOfFreedom
The degree of freedom.
Degree of Freedom

Enterprise Edition Only Feature. This method returns the t-value of the Student's t-distribution as a function of probability and degrees of freedom.


Returns the t-value of the Student's t-distribution as a function of the probability and the degrees of freedom.

Syntax

Visual Basic (Declaration)  
Public Function InverseTDistribution( _
   ByVal probability As Double, _
   ByVal degreeOfFreedom As Integer _
) As Double
Visual Basic (Usage) Copy Code
Dim instance As Statistics
Dim probability As Double
Dim degreeOfFreedom As Integer
Dim value As Double
 
value = instance.InverseTDistribution(probability, degreeOfFreedom)
C#  
public double InverseTDistribution( 
   double probability,
   int degreeOfFreedom
)

Parameters

probability
The probability for which the t-value is required. Allowable range is 0-1.
Probability
degreeOfFreedom
The degree of freedom.
Degree of Freedom

Return Value

Returns Inverse T distribution.

Example

The following sample calculates the Inverse T distribution probability.
Visual Basic Copy Code
Imports Dundas.Charting.WinControl
...

' Calculate Inverse T distribution probability
Dim result As Double = Chart1.DataManipulator.Statistics.InverseTDistribution(.05, 15)
C# Copy Code
using Dundas.Charting.WinControl;
...

// Calculate Inverse T distribution probability
double result = Chart1.DataManipulator.Statistics.InverseTDistribution(.05, 15);

Remarks

This method returns the t value for the given T distribution probability.
