Hi,

So I define a Beta Distribution in this way.

Variable<double> f = Variable.Beta(a, b);

which mathematically means

p(f) = ((a+b - 1) ! / (a-1)!) * (b-1)! * f ^(a-1) * (1-f)^(b-1)

My question is, how do i obtain the value for P( c < f < d ) ?

What I really need is an integration function of the beta density function.

Thanks for reading.
