How to use the GAMMADIST function
Author: Oscar Cronquist Article last updated on October 23, 2018
The GAMMADIST function calculates the gamma often used in queuing analysis in probability statistics.
This function is outdated and has been replaced by the GAMMA.DIST function which was introduced in Excel 2010.
Formula in cell C7:
=GAMMADIST(C3,C4,C5,C6)
Excel Function Syntax
GAMMADIST(x,alpha,beta,cumulative)
Arguments
| x | Required. |
| alpha | Required. |
| beta | Required. 1 returns the standard gamma distribution. |
| cumulative | Required. A boolean value. TRUE - cumulative distribution function FALSE - probability density function |
Comments
The GAMMADIST function returns
- #VALUE! error value if alpha, beta or x is non-numeric.
- #NUM! error value if:
- x < 0 (zero)
- alpha <= 0 (zero)
- beta <= 0 (zero)
The equation to calculate the gamma probabiltiy density function:
The standard gamma probability function:

Functions in 'Compatibility' category
The GAMMADIST function function is one of many functions in the 'Compatibility' category.
Calculates the beta distribution, it represents outcomes in the form of probabilities.
Calculates the inverse of the beta distribution.
Calculates the individual term binomial distribution probability
Calculates the probability of the chi-squared distribution.
Calculates the inverse probability of the chi-squared distribution.
Calculates the test for independence, the value returned from the chi-squared statistical distribution and the correct degrees of freedom. Use this function to check if hypothesized results are valid.
Calculates the confidence interval for a population mean, using a normal distribution.
Calculates the covariance meaning the average of the products of deviations for each pair in two different datasets.
Calculates the minimum value for which the binomial distribution is equal to or greater than a given threshold value.
Calculates the exponential distribution representing an outcome in the form of probability.
Calculates the F probability of the right-tailed distribution for two tests.
Rounds a number down, toward zero, to the nearest multiple of significance.
Calculates a value based on existing x and y values using linear regression. Use this function to predict linear trends.
Calculates the value from an F-test. The value shows if the variances from two data sets are not significantly different.
Calculates the gamma often used in queuing analysis (probability statistics).
Calculates the cumulative lognormal distribution of argument x, based on a normally distributed ln(x) with the arguments of mean and standard_dev.
Calculates the most frequent number in a cell range.
Calculates the percent rank of a given number compared to the whole data set.
Returns the quartile of a data set, use the QUARTILE function to divide data into groups.
Calculates the rank of a specific number compared to a list of numbers.
Calculates the standard deviation of a group of values.
