Hi
I am new to time series analysis using R. does anyone know what the
estimated long term average of return means. I am doing an arma model
fitting of exchange rates, and the question I have been asked is to
estimate the long term average for the returns. Is this same as the
intercept term? I model the log of the exchange rate as a ma(1) and
got 0 for the intercept.
any help will be great
If this is a homework problem, ask your instructor.
cheers,
