I have finised 55644. But I\’m not sure whether it is correct. a) in 55644 should be correct. For others, I\’m not sure.
Even when X is fixed. I still do not understand the first line of your solution in e). I’ll try with 55644.
For c), I think your answer is better although the two solutions are equivalent. So, use your result.
For e), I’m a litter bit confused with your solution, especially for the first line. How can you obtain the posterior distribution of X\\beta given y and tau. Moreover, X is also random. So, how can you then obtain the distribution of beta given Y and tau.
For 55644, I’m not sure whether I can handle all the problems, especailly d. If you think this okay, I can do this problem.
Quite difficult. If you have any question, please contact me.
