Linear mixed effects model fmri

NettetSorted by: 17. A mixed effects model has both random and fixed effects while a standard linear regression model has only fixed effects. Consider a case where you have data on several children where you have their age and height at different time points and you want to use age to predict height. If you are willing to assume that all the children ... Nettet30. jan. 2013 · The linear mixed-effects meta (or multilevel) analysis (MEMA) model can be treated as a special scenario of the general LME model (Demidenko, 2004; Viechtbauer, 2007) in the sense that the within-subject variance estimate, ˆ σ 2 i σ ^ i 2, is available and m i =1.
