Use the lognormal distribution to analyze logarithmically transformed data.

public:
 double LogInv(double Arg1, double Arg2, double Arg3);

public double LogInv (double Arg1, double Arg2, double Arg3);

Public Function LogInv (Arg1 As Double, Arg2 As Double, Arg3 As Double) As Double

Parameters

Arg1: Double

Probability - a probability associated with the lognormal distribution.

Arg2: Double

Mean - the mean of ln(x).

Arg3: Double

Standard_dev - the standard deviation of ln(x).

Returns

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:
