LOGINV(probability,mean,standarddev,accuracy,normdistaccuracy,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.
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. or or
ZOS
- The syntax is to calculate Log normal distribution in ZOS is
- 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.
Examples
- LOGINV(0.039084,3.5,1.2) = 3.9957031
- LOGINV(0.039084,3.5,1.2,0.02,0.4) = 3.5
- LOGINV(0.039084,3.5,1.2,0.02,0.9) = 5.525
- LOGINV(0.24786,6.25,3.12) = NULL
- LOGINV(0.007543,5.82,2.9) = NULL
