2. For GARCH (1, 1) model x = 0,8 lo = + ax + Bor where &t(d) and t(d) is the t-distribution with degree of d. Let @ = (w,a, b)'. i) Compute the log-likelihood function of Le). ii) = Set w= 0.02, a = 0.25, B = 0.35,01 = 0.05, d = 4, simulate the above GARCH (1, 1) process with sample size=1000 and display the time series plot. iii) Based on the above samples simulated, write a R programme to find the MLEs of O and their standard errors (SE) for the above GARCH (1, 1) model.
