Syntax. LOGNORM.INV(probability,mean,standard_dev)
Definition. This function returns the quantile of the lognormal distribution of x, where ln(x) is normally distributed with the parameters mean and standard_dev. If p = LOGNORM.DIST(x,...) then LOGNORN.INV(p,...) = x. If the probability is p, you can calculate the quantile of the lognormal distribution.
Use the lognormal distribution to analyze logarithmically transformed data.
Arguments
probability (required). A probability associated with the lognormal distribution
mean (required). The mean of the lognormal distribution
standard_dev (required). The standard deviation of the lognormal distribution
Note
If one of the arguments isn’t a numeric expression, the LOGNORM.INV() function returns the #VALUE! error.
If probability is less than 0 or greater than 1, the LOGNORM.INV() function returns the #NUM! error.
If standard_dev is less than or equal to 0, the function returns the #NUM! error.
Background. The inverse of the lognormal distribution function is:
See Also
You will find more information about lognormal distributions in the description of LOGNORM.DIST().
Example. Use the following values to calculate LOGNORM.INV():
0.039084 = the probability associated with the lognormal distribution (probability)
3.5 = the mean of ln(x) (mean)
1.2 = the standard deviation of ln(x) (standard_dev)
Figure 12-93 shows the calculation of LOGNORM.INV().
The LOGNORM.INV() function returns the quantile 4.000025 of the lognormal distribution based on the parameters shown in Figure 12-93.
Sample Files
Use the LOGINV or LOGNORM.INV worksheet in the Probability.xls or Probability.xlsx sample file. The sample files are found in the Chapter12 folder. For more information about the sample files, see the section titled Using the Sample Files.
