用多因子筛选和均生函数序列双重最优子集作降水量预报

Establishing the Precipitation Forecast by Utilizing the Double Optimized Subsets of Multi-factors Screening and Mean-value Generated Function Serial

把均生函数延拓序列作为因子加入最优子集回归方程,将因子筛选和均生函数分析相结合作最优子集回归双重分析,用于制作钦州市月降水量的预报,预报精度有所提高。

Include the continuation serial of function into the regression equation of optimized subset as factor, make the double analysis of the optimized subset regression by combining the factor screening and meanvalue generated function analysis to establish the forecast of monthly precipitation. The forecast accuracy is improved to some extent in this way.
