<SUBSET/EXCEPT/FOR qualification> where <x> is a number, parameter, or variable; <alpha> is a number, parameter, or variable that specifies the first shape parameter; <beta> is a number, parameter, or variable that specifies the second shape parameter; <c> is a number, parameter, or variable that specifies the third shape parameter; <d> is a number, parameter, or variable that specifies the fourth shape parameter; <loc> is a number, parameter, or variable that specifies the optional location parameter; <scale> is a number, parameter, or variable that specifies the optional scale parameter; <y> is a variable or a parameter (depending on what <x> is) where the computed log beta cdf value is stored; and where the <SUBSET/EXCEPT/FOR qualification> is optional. The location and scale parameters are optional (the default values are zero and one, respectively).
