mixed effect model假设了各组数据并不独立的情况,这一点后文在对比ANOVA和mixed effect model时会有详细解释。实际上教科书里介绍的重复测量within subject design ANOVA只是假设了各组数据的均值不独立情况,但并没有将实验控制的效应不独立的囊括在内,而mixed effect model很容易做到这一点。 (6).Incorporating Fixe...
Mixed Model ANOVA in SPSS To run a Mixed Model ANOVA (between and within subjects factors), you use the repeated measures linear model.The example below is from the Pisoni data. The between-subject factor is Boundary condition (consistent or inconsistent). The within-subject factor is ...

当然也可以同时设置随机截距与随机斜率 随机斜率 https://yury-zablotski.netlify.app/post/mixed-models/ 这个如何选择就看个人了,另外可以同时进行建模,然后使用anova(model1,model2, model3...)进行模型比较,看看哪个AIC比较小。 这是几个目前看到现在觉得比较重要的点,如果还有或者新理解再更新。 编辑...
结果BP(between person/subject variable, e.g., group, treatment)的结果,主效应和交互作用结果和我用repeated measures ANOVA结果一致,但WP的结果只是接近却不完全一致。 请问这是什么原因? 语句如下: MIXED result BY ID gene sex treatment intervene day /METHOD = REML /PRINT = SOLUTION TESTCOV R /FIXED...

anova(nlmefit1,nlmefit2) 可以做一个F测试而不是 LRT(即考虑到有限大小的修正)。 pchisq(iff,df=2,lower.tail=FALSE) ##分母非常大的F检验。pf(diff/2,df1=2,df2=1000000,lower.tail=FALSE) 我们不知道真正相关的df,但上面的总结表明df是40。
