Usage REAL X,A,B,Y
Y=FNF_beta(A,B,X)
Description
FNF_beta returns the value of the univariate beta probability density function with parameters a and b, f(x;a,b). F(x;a,b) is defined only for a 0 and b 0.
F(x;a,b) is defined by the expression
f(x;a,b)
Errors
FNF_beta causes an HTBasic error if its arguments are not all of type REAL or if a or b is negative.
