WorksheetFunction.Norm_Inv Method
Returns the inverse of the normal cumulative distribution for the specified mean and standard deviation.
Namespace: Microsoft.Office.Interop.Excel
Assembly: Microsoft.Office.Interop.Excel (in Microsoft.Office.Interop.Excel.dll)
Syntax
'Declaration
Function Norm_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.Norm_Inv(Arg1, _
Arg2, Arg3)
double Norm_Inv(
double Arg1,
double Arg2,
double Arg3
)
Parameters
Arg1
Type: System.DoubleProbability - A probability corresponding to the normal distribution.
Arg2
Type: System.DoubleMean - The arithmetic mean of the distribution.
Arg3
Type: System.DoubleStandard_dev - The standard deviation of the distribution.
Return Value
Type: System.Double
Remarks
If any argument is non-numeric, Norm_Inv returns the #VALUE! error value.
If probability <= 0 or if probability >= 1, Norm_Inv returns the #NUM! error value.
If standard_dev ≤ 0, Norm_Inv returns the #NUM! error value.
If mean = 0 and standard_dev = 1, Norm_Inv uses the standard normal distribution (see Norm_S_Inv(Double)).
Given a value for probability, Norm_Inv seeks that value x such that NORM_DIST(x, mean, standard_dev, TRUE) = probability. Thus, precision of Norm_Inv depends on precision of Norm_Dist(Double, Double, Double, Boolean).
