WorksheetFunction.LogNorm_Inv Method

Returns the inverse of the lognormal cumulative distribution function. Use the lognormal distribution to analyze logarithmically transformed data.

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

Syntax

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

returnValue = instance.LogNorm_Inv(Arg1, _
    Arg2, Arg3)

double LogNorm_Inv(
    double Arg1,
    double Arg2,
    double Arg3
)

Parameters

• Arg1
  Type: System.Double

  Probability - A probability associated with the lognormal distribution.

• Arg2
  Type: System.Double

  Mean - The mean of ln(x).

• Arg3
  Type: System.Double

  Standard_dev - The standard deviation of ln(x).

Return Value

Type: System.Double

Remarks

If any argument is nonnumeric, LogNorm_Inv returns the #VALUE! error value.

If probability <= 0 or probability >= 1, LogNorm_Inv returns the #NUM! error value.

If standard_dev <= 0, LogNorm_Inv returns the #NUM! error value.

The inverse of the lognormal distribution function is:
