it an AR(p) model to the data (using part 2(a), AIC or some built in R function) (b) Plot and comment on the ACF of the residuals of the model chosen in 3(a). If the model is properly fit, then we should see no autocorrelations in the residuals. Carry out a formal test for autocorrelation and comment on the results. (c) Using the appropriate predictors, fit an ARDL(p,q) model to the data and repeat step (b) in part 3
