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.WebControl<CRLF>...<CRLF><CRLF>' Calculate inverse normal distribution<CRLF>Dim result As double = Chart1.DataManipulator.Statistics.InverseNormalDistribution(.05)`

C#	Copy Code
`using Dundas.Charting.WebControl;<CRLF>...<CRLF><CRLF>// Calculate inverse normal distribution<CRLF>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.
