When the objective is to forecast a variable of interest but with many explanatory variables available, one could possibly improve the forecast by carefully integrating them.

متن کاملEvolving artificial neural networks to combine financial forecasts
We conduct evolutionary programming experiments to evolve artificial neural networks for forecast combination. Using stock price volatility forecast data we find evolved networks compare favorably with a naı̈ve average combination, a least squares method, and a Kernel method on out-of-sample forecasting ability—the best evolved network showed strong superiority in statistical tests of encompassi...
متن کاملUsing Entropic Tilting to Combine BVAR Forecasts with External Nowcasts∗
This paper shows entropic tilting to be a flexible and powerful tool for combining mediumterm forecasts from BVARs with short-term forecasts from other sources (nowcasts from either surveys or other models). Tilting systematically improves the accuracy of both point and density forecasts, and tilting the BVAR forecasts based on nowcast means and variances yields slightly greater gains in densit...
