Incomplete regularized Gamma function recursive relation












0












$begingroup$


I'm trying to found the detailed derivation of:



$Q(alpha + n, t) = Q(alpha, t) + t^alpha e^{-t} displaystylesum_{k=0}^{n-1} dfrac{t^k}{Gamma(alpha+k+1)}$



This is a relation necessary for the detailed proof of the Bayesian A/B test for countable type data. As you can see here:



Formulas for Bayesian A/B Testing



May you help me? My level is not so good in pure mathematics (and especially in functional analysis).



Thx in advance
