Two-Way ANOVA由于有两个自变量,在考虑两个变量单独对应变量影响的同时,还需要考虑交互作用 当ANOVA结果显示交互作用差异显著时,需要做每个变量在另一个变量各个水平下的显著性分析,而不能做变量的主效应分析(即使ANOVA结果显示单个变量存在显著性差异) 当交互作用差异不显著,而变量的差异显著时,才可以对相应的变量做...
其他分类分析方法类似,不再赘述。 整合以上Tests of Between-Subjects Effects、Pairwise Comparisons和Estimates三个表格的结果,就可以得到关于不同受教育程度对政治兴趣主效应的全面分析。 4.4 交互作用对照(interaction contrast) 4.4.1 交互作用对照的SPSS操...
Technical note: the “estimated marginal means” are equal to the observed means in our previous means table because we tested the saturated model (consisting of all main and interaction effects as this is the default setting in UNIANOVA).Two...
treatment combinations produced by A and B together? 3 The Two-way ANOVA Two Way ANOVA The first two of those questions are questions about main effects of the respective independent variables. The third question is about the interaction effect, the effect of the two variables consider...
This chapter introduces the concepts of main and interaction effects and uses R and WinBUGS to fit the corresponding two-way ANOVA models. The chapter illustrates R's flexibility to conduct simulations to verify the effects of sampling variation on the parameter estimates. The one-way analysis of...

上一期我们讨论了单因素方差分析,本期“科研加油站”栏目,我们一起来探讨双因素方差分析(Two-way ANOVA)。 问题与数据 某研究者已知受教育程度可以影响政治兴趣,即如果将受试者的受教育程度分为“School”、“College”和“University”3个等级(级别依次递增),他们对政治的兴趣随受教育程度的增加而增加。
Two-way ANOVA tests hypotheses about the effects of factorsAandB, and their interaction on the response variabley. The hypotheses about the equality of the mean response for groups of row factorAare H0:α1=α2⋯=αIH1:at least oneαiis different,i=1,2,...,I. ...
A two-way ANOVA analyzes the main effect of each of the independent variables on the expected outcome, in addition to the variables' relationship to each other—if there is any interaction between the independent variables. Random factors would be considered to have no statistical influence on a...
