LOGNORM.INV()/LOGINV()

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 ...
