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...
Using the linear mixed-effect regression model, we assessed whether the reaction times would be affected by a total number of dots independently from the numerical ratio between two sets of dots. The model included a total number of dots, a ratio between numerosities of the two sets and their...
In this chapter, mixed-effects regression modeling is introduced, mostly using alternation modeling as an example. It is one option to deal with cases where observations vary by groups (such as speakers, registers, lemmas) by introducing so-called random effects into the model specification. It ...
首先得了解一般线性回归，因为和mixed model 的内核是一样的，然后再看看mixed model 的原理，搞清楚对什么变量用fixed effect, 对什么上random effect。R包的话，比较常用lme4和glmer。
We present a procedure for estimating age-depth relationships in stratigraphical sequences by means of a generalized mixed-effect regression using an ancillary function for the partitioning of the fixedeffect and the random effect corresponding to the degree of representativity of the individual calibra...

Specifically, in a linear mixed-effect (LME) regression model, $${y}_{ij}=\mu + {x{\prime }}_{ij}\beta + {A}_{ij}+{C}_{ij}+{E}_{ij}$$ (1) where yij is the trait value of individual j in family i; µ is the overall mean; xij denotes a vector of covariates; ...
Suppose data for a nonlinear regression model falls into one of m distinct groups i = 1, ..., m. (Specifically, suppose that the groups are not nested.) To specify a general nonlinear mixed-effects model for this data: Define group-specific model parameters φi as linear combinations of ...
重复测量方差分析一直被用于分析这种类型的数据,因为使用其他统计技术,如多元回归(multiple regression),会违反许多统计测试的一个关键假设:独立假设。该假设指出,数据集中的观察值必须是独立的;也就是说,它们之间不能相互关联。但是,以反应时间研究为例,参与者对相同的100个试验做出反应,每个试验对应一个不同的项目(...
