Returns the inverse of the normal cumulative distribution for the specified mean and standard deviation.

double Norm_Inv(double Arg1, double Arg2, double Arg3);public double Norm_Inv (double Arg1, double Arg2, double Arg3);Public Function Norm_Inv (Arg1 As Double, Arg2 As Double, Arg3 As Double) As DoubleParameters
- Arg1
- Double
Probability - A probability corresponding to the normal distribution.
- Arg2
- Double
Mean - The arithmetic mean of the distribution.
- Arg3
- Double
Standard_dev - The standard deviation of the distribution.
Returns
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).
