WebJul 23, 2014 · By finding out the distribution of the error you can somehow simulate data similar to the original, from the regression line, by simply adding a random error (whose distribution is known) to the predicted data. Furthermore, we know from the regression line that the expected error is 0. Here is the code to implement this idea in R. Web1. I want to answer the following question, I know that I can use the arima.sim function but I am not sure how to simulate model asked: I want to simulate the following: yt =α+βt+φyt−1 +εt, εt ∼IIDN (0,1) when: alpha=1, beta=0 and theta=0.8.
