GAMMA.DIST

GAMMA.DIST(x, alpha, beta, cumulative)

Returns the probability distribution function OR the cumulative probability function for a gamma distribution.

x	The number from the distribution.
alpha	The first parameter to the distribution.
beta	The second parameter to the distribution.
cumulative	A logical value indicating the type of function to use: False (or 0) = individual probability (equal to) True (<> 0) = cumulative probability (equal to or less than)

REMARKS

* The gamma distribution is a continuous distribution
* This function is a single variable function.
* This function is a special type of Beta Distribution when
* If "alpha" = 1, then the Exponential Distribution is returned.
* If "cumulative" = False, then the height of the curve at "x" is returned.
* If "cumulative" = True, then the area under the curve to the left of "x" is returned.
* All the values are greater than zero.
* You can use the GAMMA.INV function
* You can use the GAMMA function
* You can use the BETA.DIST function
* This function was added in Excel 2010 to replace the GAMMADIST function.
