【摘要】 本文应用合并预测法对广州市垃圾产量作了预测,并对模型中的权数作了求证。结果表明,合并预测值的均方误差。较构成它的单个模型的预测误差为小。合并预测可提高预测精确度,值得推广应用。对于受多种因素影响的预测项目,由于各种预测法均有其适用特点,通常难于选用简单预测法以获得适合其所研究的特定问题,此时,合并预测常具有较好的适用性。更多还原

【Abstract】 with the method of comcalculation, we calculated the garbage product in Guangzhou City, and confirmed the weight in the model. The results show that the mean square errors of the comcalculation are far less than those of individual model formed. The method of comcalculation should be popularized because it can improve the calculating precision. Since various calculating methods have its characteristics, for the calculating items affected by many factors, its is difficult to select simple calculating methods to get specific problem fitted the study However, the comcalculation is better useful in these problems.更多还原
