| Abstract: | 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,T inspection,χ2 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. |
