Q2. Logarithmic model with no intercept This question may be handwritten and then scanned to pdf, or typed up. Consider the logarithmic regression model with no intercept term Y = B log(xi) + Eig 1,2,. where ei ~ N(0,0%) are independent for i n. The parameters of this model are 0 = (1,02)T. (a) Write down the likelihood function and the log-likelihood function. [5 marks] (b) Find the score vector. [3 marks] (c) Find the maximum likelihood estimator for B and o2. (4 marks (d) Find the Fisher information matrix about 0. [8 marks] Q2. Logarithmic model with no intercept This question may be handwritten and then scanned to pdf, or typed up.
