Enterprise Edition Only Feature. This method returns the probability for the standard normal cumulative distribution function.

Returns the normal cumulative distribution for the specified mean and standard deviation. This function has a very wide range of applications in statistics, including hypothesis testing.

Syntax

Visual Basic (Declaration)
Public Function NormalDistribution( _ ByVal zValue As Double _ ) As Double

Visual Basic (Usage)	Copy Code
`Dim instance As Statistics Dim zValue As Double Dim value As Double value = instance.NormalDistribution(zValue)`

C#
public double NormalDistribution( double zValue )

Parameters

zValue: The Z value for which the probability is required.
Z Value

Return Value

Returns value from standard normal cumulative distribution function.

Example

The following sample calculates the normal distribution.

Visual Basic	Copy Code
`Imports Dundas.Charting.WebControl<CRLF>...<CRLF><CRLF>' Calculate normal distribution<CRLF>Dim result As Double = Chart1.DataManipulator.Statistics.NormalDistribution(1.96)`

C#	Copy Code
`using Dundas.Charting.WebControl;<CRLF>...<CRLF><CRLF>// Calculate normal distribution<CRLF>double result = Chart1.DataManipulator.Statistics.NormalDistribution(1.96);`

Remarks

This method returns the normal cumulative distribution for the specified Z value. The standard normal distribution has a mean of 0 (zero) and a standard deviation of one.

The standard normal distribution has a wide range of applications in statistics, including hypothesis testing.
