3. For each day in 2001, calculate the 1-day, 1%VaRs using the following methods:

(a) RiskMetrics, that is, normal distribution with an exponential smoother on variance using the weight, λ = 0.94;

(b) GARCH(1,1)-˜t

(d) with parameters estimated in Chapter 4, question 5;

(c) historical simulation; and

(d) filtered historical simulation (Excel Hint: Use the sampling tool in data analysis.) Use a 251-day moving sample. Plot the VaRs along with the return.
