GAMMA.DIST

This function returns the gamma distribution.

Syntax

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

Arguments

This function has these arguments:

Argument	Description
x	[Required] Value at which to evaluate the distribution
alpha	[Required] Alpha parameter of the distribution
beta	[Required] Beta parameter of the distribution
cumulative	[Required] Logical value that determines the form of the function If cumulative is TRUE, then this function returns the cumulative distribution function; if FALSE, it returns the probability density function.

Remarks

The equation for this function is:

Examples

GAMMA.DIST(A5,1,3,FALSE)

GAMMA.DIST(R5C1,2,1,TRUE)

GAMMA.DIST(4,3,2,TRUE) gives the result 0.3233235838169362

GAMMA.DIST(4,3,2,FALSE) gives the result 0.1353352832366127
