Addressing Collinearity Among Competing Econometric Forecasts: Regression Based Forecast Combination Using Model Selection.
Based on Monte Carlo simulations using both stationary and nonstationary data, a model selection approach which uses the SIC to select a "best" group of forecasts in the context of forecast combination regressions dominates a number of other techniques, including the standard t-statistic approach which is commonly used in practical applications.
