LOGNORM.INV(probability, mean, standard_dev)

Returns the inverse of the probability distribution function for a lognormal distribution.

probabilityThe probability associated with the distribution.
meanThe arithmetic mean of the distribution.
standard_devThe standard deviation of the distribution.

* This function was added in Excel 2010 to replace the LOGINV function.
* The lognormal distribution is a [[continuous distribution]]
* ln(x) is normally distributed with parameters mean and standard_dev
* For the Microsoft documentation refer to support.microsoft.com

1=LOGNORM.INV(0.029084, 3.5, 1.2) = 3.410
2=LOGNORM.INV(0.5, 2, 1) = 7.389
