Consider the likelihood function kcyc-1 L (K, C; V1, V2, ... . Vn) = (1 + y.C)k+1 i=1 Where c and k are positive numbers, and y; can be found in "Question2.cav". a) Write down the log-likelihood function. b) Write down the corresponding maximum likelihood formulation. c) Derive the gradient and Hessian of the log-likelihood function
