2. Let Y1, ..., Yn be iid random variables with E[Y;]

2. Let Y1, ..., Yn be iid random variables with E[Y;] = M; and Var[Y,] = 2emi. (a) Write down the quasi-score for (Y1, ..., Y). (b) Compute the quasi-likelihood and quasi-deviance for (Yi, ..., Yn). (c) Find the link function, g (u;), such that g'(u;)V (M;) = 1. (d) Find a reduced expression for the quasi-deviance based on the maximum likelihood estimate with identity link function in the case where the design matrix contains an intercept term
