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

Version Available

This function is available in Spread for Windows Forms 11.0 or later.
