I'm taking Econometrics 2 this semester (time series, ARMA, ADF etc) and I'm having a lot of trouble understanding what's going on, particularly in some of the later chapters (how did my autoregression transform into an equation full of lag operators, phi and a whole assortment of other greek letters?!). In other words, I need some serious help, since the professor isn't available all the time. Admittedly, I also feel embarrassed asking him certain questions that could make me look like the ultimate noob. If possible, I'd like to consult some of you experts via PM or even MSN Messenger.

I'd like to give back in some form of payment, maybe some GOGames or Gamersgate blue coins, but it definitely won't be much since I'm only subsisting on $200 a month from tuition. Still, I hope there are some good Samaritans around. Let me know if you want to help out a struggling student :D

-edit- Also, 1000 rep! *fistpump*
