摘要
研制了 F分布、χ2 分布和 t分布的编程算法 ,并在此基础上提出了新的统计检验法 ,免除了繁琐的手工查算 ,解决了自动分析中自由度随机变动时 ,传统检验法不能准确检验的难题 ,从而实现了统计分析自动化 ,精确筛选因子建立预报方程。这一工作是对传统检验方法的重大改进 。
The programming algorithm of the F distribution functions was described.The new statistical verification method introduced not only advoids the trivial table look up but also overcomes the inaccuracy by changing the degree of freedom randomly in the automatical analysis for the traditional verification method.So the regression equations developed by screening predictors accurately and the statistical verification can be automatized.The traditional statistical verification method is improved by this new statistical verification method which is adoptive for meteorological stations in China.
