1. Consider the following regression model: yi = Bo+ Bitu+ . . . + Bpkip + ci, i = 1, . .., n, where e are i.i.d. ~ N(0, 62). (i) Give the MLE of B and o2, where B = (Bo, B1, . .., Bp) . (ii) Derive explicitly the expression of AIC and BIC. Confirm that the derived AIC differ from n In(82) + 2jm by the constant n(In(27) + 1)
