Bir lmer modelden etkilerin tekrarlanabilirliğinin hesaplanması
Bu yazıda , karışık etki modellemesi ile bir ölçümün tekrarlanabilirliğini (diğer bir deyişle güvenilirlik, sınıf içi korelasyon) nasıl hesaplayacağımı anladım . R kodu şöyle olurdu: #fit the model fit = lmer(dv~(1|unit),data=my_data) #obtain the variance estimates vc = VarCorr(fit) residual_var = attr(vc,'sc')^2 intercept_var = attr(vc$id,'stddev')[1]^2 #compute the unadjusted repeatability R = …
