Formula Generator - LOGNORM.DIST function

The LOGNORM.DIST function returns the probability or cumulative probability of a value occurring in a log-normal distribution. It is commonly used in statistics and finance to model data that is positively skewed and has a long tail. The function takes three arguments: x, which is the value for which we want to calculate the probability or cumulative probability; mean, which is the mean of the distribution; and standard_deviation, which is the standard deviation of the distribution.

LOGNORM.DIST formula syntax.

The LOGNORM.DIST function in Excel calculates the cumulative distribution or probability density of a log-normal distribution. Its syntax is as follows: LOGNORM.DIST(x, mean, standard_dev, cumulative) - x: This is the value at which you want to evaluate the log-normal distribution. - mean: This is the mean of the logarithm of the distribution. - standard_dev: This is the standard deviation of the logarithm of the distribution. - cumulative: This is a logical value that determines the form of the function. If cumulative is TRUE, the function calculates the cumulative distribution function. If cumulative is FALSE, the function calculates the probability density function. Note: The mean and standard_dev arguments must be positive numbers. Example usage: =LOGNORM.DIST(10, 2, 0.5, TRUE) This formula calculates the cumulative distribution of a log-normal distribution with a mean of 2, standard deviation of 0.5, and evaluates it at the value of 10.

Use Cases & Examples In these use cases, we use the LOGNORM.DIST formula to calculate the cumulative probability of a given value in a lognormal distribution, based on the mean and standard deviation.
