I've been reading Heij and Verbeek's book, but I still don't know how to know to calculate if an equation has a unit root or not. I understand ing most of the concepts behind time series theory isn't hard, but the math behind it isn't so trivil. Any tips? I Also do not understand the algebric step to step Heij goes through in pic related. Sorry if I posted in the wrong board
