LOGNORM.DIST |
|
This function returns the cumulative natural log normal distribution of x, where LN(x) is normally distributed with the specified mean and standard deviation. Analyze data that has been logarithmically transformed with this function.
Syntax
LOGNORM.DIST(x,mean,stdev,cumulative)
Arguments
This function has these arguments:
Argument |
Description |
x |
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) |
cumulative |
A logical value that determines the form of the function. If cumulative is TRUE, this function returns the cumulative distribution function; if FALSE, it returns the probability density function |
Remarks
If any argument is nonnumeric, this function returns the #VALUE! error value.
The equation for the lognormal cumulative distribution function is:
LOGNORM.DIST(x,µ,o) = NORM.S.DIST(1n(x)-µ / o).
Data Types
Accepts numeric data for x, mean, and stdev arguments. Accepts TRUE or FALSE for cumulative. Returns numeric data.
Examples
LOGNORM.DIST(0.92,B8,G22,A5)
LOGNORM.DIST(42,2,1.2,TRUE) gives the result 0.9261995869896625
