Obliczanie powtarzalności efektów z modelu Lmer

Właśnie natknąłem się na ten artykuł , który opisuje, jak obliczyć powtarzalność (aka niezawodność, aka korelacja wewnątrzklasowa) pomiaru za pomocą modelowania efektów mieszanych. Kod R byłby następujący: #fit the model fit = lmer(dv~(1|unit),data=my_data) #obtain the variance estimates vc =...
