关于NBA赛程利弊因素的分析与评价模型

本文考虑球队间胜率、主场优势、休整时间三个因素来分析赛程对某一支球队的利弊。建立主场优势、休整时间同球队间胜率的变化量之间的多元线性回归模型:△Pij=β0+β1x1+β2x2+β3x3+β4x4+ε。通过赛程数字化方法得出某一球队的回归变量矩阵x1、x2、x3、x4]及预测变量矩阵△Pij],做回归分析得到回归系数并定义了数量指标评价赛程对球队的利弊,并给出了计算某一球队值的算法。

Analysis of Disadvantage and Advantage Factors and Evaluation Model about NBA Schedules

This paper analyzes the disadvantage and advantage to a team, considering the factors of win rate among teams, home advantage, time to rest and refresh and establishes multivariate linear regression model of variation of win rate among teams, home advantage, time to rest and refresh：ΔPv=β0＋β1x2＋β2x2＋β3x3-β4x4＋ε, and achieves regressor variable matrix of one team：x1,x2,x3,x4]and predictor variable matrix：ΔPij] through the method of schedules quantization, makes regression analysis and get regression coefficient, defines the quantity index disadvantage and advantage to a team.
