LOGINV

LOGINV(probability, mean, standard_dev)

Returns the probability of getting greater than a particular value in a lognormal distribution.

probability	The probability associated with the lognormal distribution.
mean	The arithmetic mean of the distribution.
standard_dev	The standard deviation of the distribution.

REMARKS

* LOGNORM.INV was added in Excel 2010 to replace this function.
* The lognormal distribution is a continuous distribution.
* Use the lognormal distribution to analyze logarithmically transformed data.
* If p = LOGNORMDIST(x,) then LOGINV(p,) = x.
* If any of the arguments are not numeric, then #VALUE! is returned.
* If "probability" < 0, then #NUM! is returned.
* If "probability" > 1, then #NUM! is returned.
* If "standard_dev" <= 0, then #NUM! is returned.
* In Excel 2010 the accuracy of this function was improved.
