lmerモデルからの効果の再現性の計算
混合効果モデリングによる測定の再現性(別名信頼性、別名クラス内相関)の計算方法を説明するこの論文に出会ったばかりです。Rコードは次のようになります。 #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$id,'stddev')[1]^2 #compute the unadjusted repeatability R = intercept_var/(intercept_var+residual_var) #compute n0, the repeatability adjustment n = as.data.frame(table(my_data$unit)) k = nrow(n) N = sum(n$Freq) n0 = (N-(sum(n$Freq^2)/N))/(k-1) #compute the adjusted repeatability Rn = …
