probability
The probability (alpha value). Allowable range is 0-1.
Probability

Enterprise Edition Only Feature. This method returns the inverse of the standard normal cumulative distribution.


Returns the inverse of the normal cumulative distribution for the specified mean and standard deviation.

Syntax

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

Parameters

probability
The probability (alpha value). Allowable range is 0-1.
Probability

Return Value

Returns value from inverse standard normal cumulative distribution function.

Example

The following sample calculates the inverse of the normal distribution.
Visual Basic Copy Code
Imports Dundas.Charting.WinControl
...

' Calculate inverse normal distribution
Dim result As double = Chart1.DataManipulator.Statistics.InverseNormalDistribution(.05)
C# Copy Code
using Dundas.Charting.WinControl;
...

// Calculate inverse normal distribution
double result = Chart1.DataManipulator.Statistics.InverseNormalDistribution(.05);

Remarks

This method returns the F value for the given F distribution probability.

It is assumed that the distribution has a mean of 0 (zero) and a standard deviation of one.

Requirements

Target Platforms: Windows 98, Windows NT 4.0, Windows Millennium Edition, Windows 2000, Windows XP Home Edition, Windows XP Professional, Windows Server 2003 family, Windows Vista, Windows Server 2008 family
