Computing:
(1) R and SCA will be used for most analyses in class. SCA is available on
      all GSB machines. For R, the recent version 2.6  or higher is recommended.
(2) S-Plus is also used mainly for Kalman filtering.
(3) Students may use other packages, e.g., SAS, SPSS, MATLAB, 
      to answer hw questions.

Some commands for  SCA and R:

R code for out-of-sample forecast: r-backtest.txt
R code for out-of-sample forecast error transform: r-foreden.txt
