摘要
描绘变量间统计关系的数学模型是近似公式,其正确性与精度必须通过统计检验验证.统计检验的方法很多且各具优势,着重介绍土建工程变形分析中常用的相关性检验、T检验、χ2检验等,并佐以实例阐明应用范围和具体推演方式,旨在运用经典数学理论指导施工控制,实现数学理论与工程实践的成功结合.
The statistical relationship between describe variable is approximately expressions. The validity and precision of the model need validate by statistical inspection methods, which has a lot of advantages. The article will emphasize introducing some usual methods, which were used for transmutation analysis of construction projects, such as pertinency inspection, ＂I＂ inspection, χ^2 inspection, etc. It also elucidates application confine and idiographic calculation. The aim of this article is implementing the successful combination between mathematical theories and project practice by guidance of classical mathematical theories on construction domination.
