|3 marks| The gamma distribution has the probability density function f(yi e, B) = {B*/T(a)}y~" exp(By), where y > 0,a > 0 and 7 > 0 and I'() is the gamma function. You may assume that (i) the mean, u, of the gamma distribution is given by p = o//3; and (ii) the gamma distribution is a generalised linear model with a scale/dispersion parameter = 1/a, in the notation of the Generalised Linear Model F:0,4) = {\"E + oty ,a:-}} What is the canonical link function when the generalised linear model is gamma
