For a given probability, the Excel LOGINV function computes the inverse of the Cumulative Log-Normal Density Function of x.
Syntax :
=LOGINV( probability, mean, standard_dev )
Parameters :
Probability –
mean –
standard dev –
Example :
The Inverse Log-Normal Continuous Distribution Function of x is seen in the graphic on the right. ln(x) has a mean of 2 and a variance of 0.2.
If you wish to compute the value of x given a probability of 0.3, use the Excel Loginv function, as shown below:
=LOGINV( 0.3, 2, 0.2 )
This gives the result 6.653346076.
