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.
  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

  1. LOGINV(0.039084,3.5,1.2) = 3.9957031
  2. LOGINV(0.039084,3.5,1.2,0.02,0.4) = 3.5
  3. LOGINV(0.039084,3.5,1.2,0.02,0.9) = 5.525
  4. LOGINV(0.24786,6.25,3.12) = NULL
  5. LOGINV(0.007543,5.82,2.9) = NULL
