摘要
Based on theory of weighted arithmetic average prediction method,the paper introduces the optimal weighted geometric combined prediction method,arrives arsome important conclusions about judging existence of optimal methods and deleting redundant methods·provides the solution ro an optimal weighted geometric combined model,and finally rhc author make an error analysis and comparison between optimal weighted average arithmetic combined prediction and optimal weighted geometric average combined prediction.
