Definition of Beta Type II Distribution
A continuous random variable $X$ is said to have a beta type II distribution with parameter $\alpha$ and $\beta$ if its p.d.f. is given by
$$ \begin{aligned} f(x) &=\frac{1}{B(\alpha,\beta)}\cdot\frac{x^{\alpha1}}{(1+x)^{\alpha+\beta}}; x>0, \alpha, \beta > 0. \end{aligned} $$
where,

$B(\alpha,\beta) =\frac{\Gamma \alpha \Gamma \beta}{\Gamma (\alpha+\beta)}=\int_0^1 x^{\alpha1}(1x)^{\beta1}\; dx$
is a beta function and 
$\Gamma \alpha$
is a gamma function.
