Combination of Economic Forecasts: An Odds-Matrix Approach
用国民生产总值预测数据测试了一种新的经济预测组合方法：赔率矩阵法，结果显示该方法比其他方法更准确，尤其适用于数据非平稳或稀疏的情况。
In this article, we test a new method of combining economic forecasts, the odds-matrix approach, using Clemen and Winkler's (1986) data on gross-national-product forecasts. For these data, the results show that the odds-matrix method is more accurate than each of the other methods tested and can be expected to be especially useful when data are nonstationary or sparse.
