Multiple Regression What is multiple regression? Multiple regression is regression analysis with more than one independent variable. It is used to quantify the influence of two or more independent variables on a dependent variable. The general multip…

SPSS超详细操作:分层回归(hierarchical multiple regression) 1.问题与数据 最大携氧能力(maximal aerobic capacity, VO2max)是评价人体健康的关键指标,但因测量方法复杂,不易实现.某研究者拟通过一些方便.易得的指标建立受试者最大携氧能力的预测模型. 目前,该研究者已知受试者的年龄和性别与最大携氧能力有关,但这种关联强度并不足以进行回归模型的预测.因此,该研究者拟逐个增加体重(第3个变量)和心率(第4个变量)两个变量,并判断是否可…
