Warning: The hard deadline has passed. You can attempt it, but you will not get credit for it. You are welcome to try it as a learning exercise.

This assignment refers back to the Week 7 R programming assignment. You should complete that first as the questions in this assignment will relate to the output generated by your code.

Question 1

(5) What is the estimate of SE^(σ^2FMAGX)?

Question 2

(5) What is SE^(ρ^VBLTX,FMAGX)?

Question 3

(15) For which assets do you reject the null hypothesis H0:μi=0 vs. H1:μi≠0 at the 5% significance level? Check all that apply.

Question 4

(15) For which assets do you reject the null hypothesis H0:ρij=0 vs. H1:ρij≠0 at the 5% significance level? Check all that apply.

Question 5

(15) For which assets do you reject the null hypothesis H0:rit∼normal vs. H1:rij∼not normal at the 5% significance level? Check all that apply.

Question 6

(20) For which of the following parameters do you expect your bootstrap SE value to be accurate? (Hint: Do the bootstrap distributions look normal?)

Question 7

(10) Under the assumptions of the Constant Expected Return Model, what is E[r¯2i], where r¯i=1T∑Tt=1rit?
(You may find the relation Var(Y)=E(Y2)−E(Y)2 useful.)
