The inverse incomplete beta function calculates x such that:

y=Ix(a,b)=Γ(a+b)Γ(a)Γ(b)0xta1(1t)b1dtWhere Γ is the gamma function and Ix is the incomplete beta functiony = I_x(a,b) = \frac{\Gamma(a+b)}{\Gamma(a)\Gamma(b)}\int_{0}^{x}t^{a-1}(1-t)^{b-1}dt\newline\newline \text{Where $\Gamma$ is the gamma function and $I_x$ is the incomplete beta function}
