Hi, I have a programming problem in Eviews. I want to forecast a series, called y, from an equation, generating a series called y1. Then I want to control the growth rate of y1, for example, the highest growth rate is set to 2%. A pseudo program code could look like the following growth_rate = 0.02 ...
