分层回归中的每个模型都相当于一个强制纳入变量(Enter method)的多重线性回归模型,具体评价指标也相似: Measures of model ‘fit’ for the three models: 分别评价本研究中3个模型的拟合程度 R2是多层回归的重要指标,反映自变量解释因变量变异的程度。从上表可以看出,随着自变量数量的增加,模型1-3的R2逐渐增加,分...
研究者拟判断逐个增加自变量(weight和heart_rate)后对因变量(VO2max)预测模型的改变。针对这种情况,我们可以使用分层回归分析(hierarchical multiple regression),但需要先满足以下8项假设: 假设1:因变量是连续变量 假设2:自变量不少于2个(连续变量...

Hierarchical Models Synonyms Generalized linear mixed effects model;Hierarchical linear model;Linear mixed effects model;Multilevel model Definition Hierarchical models are statistical models with parameters that vary at more than one level of analysis. Hierarchical models have been developed and widely used...
Since multiple models were used for the regression analysis—one for each functional domain—we countered alpha inflation due to multiple tests using a conservative Bonferroni correction procedure and report p-values well below the .05. The regression models helped us determine the best predictors of...
