| 摘 要： | 针对运动成绩变化规律的模糊性、未知性等，运用灰色系统理论的灰色模型方法，建立了男子跳远全国纪录的等维灰数递补GM(1，1)预测模型，并进行后验差检验和关联度分析。结果表明，预测模型精度为一级(GOOD)。同时，运用该预测模型对2002年跳远成绩进行预测。

| Abstract: | This article applies the grey model approach in the grey system theory to set up the Same-distance Grey munmer's Step-supplement forecasting model GM(1,1)of the national record of long jump,begin directed against the ambiguity,unknown and so on.It also performs the examinnation of posterior difference and analysis of the relative degree.It turns out the precision of forecasting model is equal to first class(GOOD).At the same time,this model has been applied to forecast the sport achievement of 2002. |
