LOGINV (probability,mean,standard_dev,accuracy,somenormdistaccuracy,recursivelimit)

• is the probability associated with lognormal distribution
• is the mean value of ln(x)
• is the standard deviation of ln(x).
• gives accurate value of the solution.
• LOGINV(), returns the inverse of the lognormal distribution.

Description

• This function gives the inverse value of Log-normal Cumulative Distribution.
• This distribution is the Continuous Probability Distribution.
• Log-normal Distribution is also called Galton's distribution.
• A random variable which is log-normally distributed takes only positive real values.
• If ,

then .

• This function will give the result as error when
Any one of the argument is non-numeric.
