Use GAMMAP to calculate the regularized gamma function P(a, x). The equation for this function is:
Where
Syntax
SELECT [wctStatistics].[wct].[GAMMAP] (
<@A, float,>
,<@X, float,>)
Arguments
@A
a value to be passed to the function. @A is an expression of type float or of a type that can be implicitly converted to float.
@X
a value to be passed to the function. @X is an expression of type float or of a type that can be implicitly converted to float.
Return Types
float
Remarks
· If @A <0 or @X is < 0, GAMMAP returns an error.
· GAMMAP(@A, @X) + GAMMAQ(@A, @X) = 1
Examples
Select wct.GAMMAP(5,2)
This produces the following result
