Question 7 Suppose Alana has personal wealth of $10,000 and there is a probability of 0.2 of losing her car worth $6,400 in an accident. Her utility (of wealth) function is given by u(w) = w0.5, where w is wealth. (a) What is Alana's expected wealth, expected utility, and utility of expected wealth? If she can insure "fully", and if this insurance is fair, how much would it cost her? (b) What is the maximum amount Alana would be prepared to pay for...

Generate data of length n=100 from a Gaussian AR(2) model with phi1=0.5 and phi2=0.2 and input variance sigma^2=1. Afterwards, pretend the values of phi1, phi2 and sigma^2 are unknown. i. Use the R function ar() to fit an AR(p) model to your data. As options for the ar() function, first use aic = TRUE. What estimated order did aic minimization give for your data? Try three different fitting methods, method="yule-walker", method="ols"and also method="mle". Do you see significant differences between the...
