1. (16 points) This question asks you about the relationship between ARMA, AR, and MA models. (a) Transform the following ARMA(1,1) model into a MA(60) model. What is the required condition on the parameters and for the transformation to work? (8 points) rt = ört-1 + at + Bat-1. (b) Transform the following ARMA(1,1) model into an AR(c) model. What is the required condition on the parameter 0 and for the transformation to work? (8 points) rt = prt-1 + a + Bat-1
