女子100m栏世界、全国纪录的等维灰数递补GM(1,1)模型及其预测

Equal Dimensions Gray Number Pattern and Its Forecast of Sportswoman's Word and State Records in 100—metre Hurdles

本文运用灰色系统理论中的灰色模型方法,建立了女子100m 栏世界和全国纪录的等维灰数递补 GM(1,1)预测模型,并进行了后验差检验,结果表明,模型的精度均为一级(GOOD),预测模型精度很高,具有一定的实用价值。同时用该模型对2005年该项运动成绩进行了预测。

The Equal Dimensions Gray Number Forecast Pattern of Sportswoman's World and State Records in 100—mertre Hurdles was set forth in this paper by using the method of Gray Pattern in Gray System Theory,its aftercheck differences are examined with the result showing that the precision is up to grade one.Then it is concluded that the Forecast Pattern has some sport in 2005 are calculated by means of this pat- tern.
