Subject:      Find a regression model who's predictions are not that volatile
Content-Type: text/plain; charset=us-ascii

I haev a regression model with two independent variables. these two variables have historically proved to be a good predictor since the Adjusted R^2 = .707. However, for the most recent month and the month before, although the model has been predicting the correct movement of the independent variable, it has been overestimating the absolute value of that move. I'm trying to find a different regression model that may be less volatile so that it wouldn't predict such big changes but still be a decent predictor. I tried quadratic terms, I tried taking the ln of the dep variable but both cases I still get the high predicted value. Any ideas how I can find such a less-volatile model? Thanks guys! -- View this message in context: Sent from the SPSSX Discussion mailing list archive at
