Inverse of Incomplete Beta Function 1
Let $a,b,p,q$ be positive real numbers and $0 < p,q < 1$, this calculator evaluates the following two functions.
- Inverse of regularized incomplete beta function on $x$, i.e. find $x$ such that $\displaystyle p=\mathbf{I}_x(a,b)=\frac{1}{\mathbf{B}(a,b)}\int_0^x t^{a-1}(1-t)^{b-1}\;dt$
- Inverse of complement regularized incomplete beta function on $x$, i.e. find $x$ such that $q=1-\mathbf{I}_x(a,b)$
