WorksheetFunction.LogInv Method
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 LogInv ( _
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.LogInv(Arg1, Arg2, _
Arg3)
double LogInv(
double Arg1,
double Arg2,
double Arg3
)
Parameters
Arg1
Type: System.DoubleProbability - a probability associated with the lognormal distribution.
Arg2
Type: System.DoubleMean - the mean of ln(x).
Arg3
Type: System.DoubleStandard_dev - the standard deviation of ln(x).
Return Value
Type: System.Double
Remarks
Important
This function has been replaced with one or more new functions that may provide improved accuracy and whose names better reflect their usage. This function is still available for compatibility with earlier versions of Excel. However, if backward compatibility is not required, you should consider using the new functions from now on, because they more accurately describe their functionality. For more information about the new function, see the LogNorm_Inv(Double, Double, Double) method.
If any argument is nonnumeric, LogInv returns the #VALUE! error value.
If probability <= 0 or probability >= 1, LogInv returns the #NUM! error value.
If standard_dev <= 0, LogInv returns the #NUM! error value.
The inverse of the lognormal distribution function is:
