1. Consider the exponential GLM where the responses { Y,, 1 0. Hi (a) Choose the logarithmic link function and carefully state the model when the covariates are fri, 1 ign). (b) Write down the expression for the log-likelihood function of the standard model. (c) Consequently, write down the equations that must be solved for estimating the parameters. (d) Obtain an algebraic expression of the residual deviance for this GLM. Prove that the residual deviance is always nonnegative. The above GLM is used to model the following data on survival times {Vi; 1
