Please use RStudio solve this question and use the seed set.seed(10202016). just need post the screenshot.

4. Consider the ARMA (2,1) process given by where wt are iid standard Normal random variables (a) Use arima.sim) to simulate 200 observations from this process and plot it (b) Take the simulated data and use the arima) function to fit an ARMA (2,0), an ARMA(0,1) an ARMA (1,1), an ARMA(2,), and ARMA (3,2) process to the simulated data. Report n each fitted model and compa ficients. 4.
