New dominant forecasting method and redundant measure are defined for combination forecasting method with generalized weight arithmetic average, based on error of power of p.
从P次幂误差的概念出发，提出了广义加权算术平均组合预测法新的预测方法优超和冗余度的定义。
Some forecasting procedures sum the absolute values of the errors and may report this sum, or divide it by the number of forecast attempts to produce the average forecast error.
一些预测程序总计错误的绝对值而且可能报告这总数， 或藉着预测尝试的数字分开它生产平均的预测错误。
Practical results show that the proposed method lowers both average error and maximum error and improves forecasting precision.
对预测结果的分析表明，多点外推法不仅减少了平均误差，也使最大误差降低，能有效提高预测精度。
