Question 7 The Gamma distribution Gamma(o, B) is given by fA (A; Q, B) =. Baja-le- BX where a and B are parameters of the distribution, and (.) is the Gamma function (see Lecture 1 if you don't remember what this function is), with derivative denoted by '(.). Show that it is a conjugate prior of Poisson (X), i.e., when the observations X; for 1
