Hi all, does anyone know of a function that would calculate AIC or AICc for a system of equations. I have several systems and I have individual AIC values but I need a global one to assess amongst several systems of equations. The systems are very similar to, but not exactly like VAR groups of equations. I have the printout from one of the systems below. Many thanks in advance, Darius.
