Dear Professors, Please, I need you to put me through on two things. First, how can I save a correction matrix using hansl syntax. Secondly, I want to perform a forecasting after estimating through maximum likelihood. For example, as shown below, mle ll = "likelihood function" series e = GDPrate - constant params constant end mle If I want to perform the dynamic forecast or one step ahead forecast, what is the additional syntax needed. I hope to receive your response soon. Regards Timmy John
