路桥施工投标报价水平与中标率非线性分析

Non-Linear Analysis about Reporting Price and Winning Mark Frquency of Entering A Bid of Highway and Bridge Construction

本文依据以往路桥施工投标的报价和中标次数等情报资料，运用数理统计理论计算报价水平与中标率统计值，并绘制成散点分布图，确定报价水平与中标率非线性方程，并对其用最小二乘法原理进行回归分析和显著性检验。

ccording to the information of reporting price and winning wark about entering a bid of highway and bridge construction, this paper calculates reporting price lever and winning mark frequency using theory of statistics, draws the diagram of loose point, establishes nonlinear equation of reporting price lever and winning mark frequency, and carries out regrssion analysis and notable inspection by the principle of minimun two-multiplication.
