WorksheetFunction.Norm_Dist Method

  • Article

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

Namespace:  Microsoft.Office.Interop.Excel
Assembly:  Microsoft.Office.Interop.Excel (in Microsoft.Office.Interop.Excel.dll)

Syntax

'Declaration
Function Norm_Dist ( _
    Arg1 As Double, _
    Arg2 As Double, _
    Arg3 As Double, _
    Arg4 As Boolean _
) As Double
'Usage
Dim instance As WorksheetFunction
Dim Arg1 As Double
Dim Arg2 As Double
Dim Arg3 As Double
Dim Arg4 As Boolean
Dim returnValue As Double

returnValue = instance.Norm_Dist(Arg1, _
    Arg2, Arg3, Arg4)

double Norm_Dist(
    double Arg1,
    double Arg2,
    double Arg3,
    bool Arg4
)

Parameters

  • Arg1
    Type: System.Double

    X - The value for which you want the distribution.

  • Arg2
    Type: System.Double

    Mean - The arithmetic mean of the distribution.

  • Arg3
    Type: System.Double

    Standard_dev - The standard deviation of the distribution.

  • Arg4
    Type: System.Boolean

    Cumulative - A logical value that determines the form of the function. If cumulative is true, Norm_Dist returns the cumulative distribution function; if false, it returns the probability mass function.

Return Value

Type: System.Double

Remarks

If mean or standard_dev is nonnumeric, Norm_Dist returns the #VALUE! error value.

If standard_dev ≤ 0, Norm_Dist returns the #NUM! error value.

If mean = 0, standard_dev = 1, and cumulative = true, Norm_Dist returns the standard normal distribution, Norm_S_Dist(Double, Boolean).

The equation for the normal density function (cumulative = false) is:

When cumulative = true, the formula is the integral from negative infinity to x of the given formula.
