i do not understand the exact information the term "innovation process" has.
i mean, many articles begin with these kinds of assumptions: "the source signals are an innovation process","the source signals are an ARMA or AR models" and etc... and much of them do net clearify the exact reasons for such assumptions.
i already read populis book and i am familiar with the concept but i dont get it, what would happen if "the sources were not innovation or ARMA or AR"? what are the suitable properties of these assumptions?!
tnx in advance.
