This function returns the inverse of the lognormal cumulative distribution function of x, where LN(x) is normally distributed with the specified mean and standard deviation.
LOGNORM.INV(prob,mean,stdev)
This function has these arguments:
Argument | Description |
---|---|
prob | Value at which to evaluate the function |
mean | Value of mean of natural logarithm of x, LN(x) |
stdev | Value representing the standard deviation of LN(x) |
This function calculates the inverse of the lognormal cumulative distribution functions, so if p = LOGNORM.DIST(x,...) then LOGNORM.INV(p,...) = x. The #VALUE! error value is returned if any argument is nonnumeric.
Accepts numeric data for all arguments. Returns numeric data.
LOGNORM.INV(0.92,B8,G22)
LOGNORM.INV(0.88,2,1.2) gives the result 30.264764580330958
