imation Consider the GWN Model for cc returns = , = 1, , (1) iid (0, 2 ) (2) cov(, ) = , (3) cov(, ) = 0 for (4) where denotes the cc return on asset ( = AMZN, , SBUX). 1. Using sample descriptive statistics, give estimates for the model parameters , 2 , , ,, ,. 2. For each estimate of the above parameters (except ,) compute the estimated standard error. That is, compute se( ), se( 2 ), se( ), and se( ). Briefly comment on the precision of the estimates. Hint: the formulas for these standard errors were given in class, and are given in the lecture notes on the constant expected retu
