Blue, blup ve varyans unsurlarının tahminlenmesinde outlier seçimi
Bu araştırmada Henderson'un Karışık Model Eşitliği'nde yer alan parametreler için outlier seçimi amaçlanmıştır. Bu amaçla 386 veri kullanılmıştır. Sabit etkiler tahmininde outlier olan bazı gözlemler şansa bağlı etkilerin tahmininde outlier özelliğini taşımamıştır. Ayrıca sabit ve şansa bağlı etkilerin tahmininde (BLUE ve BLUP) outlier olan bazı gözlemler varyans unsurlarının tahmininde aynı özelliği göstermemiştir. Çok az gözlem hem sabit ve şansa bağlı hem de varyans unsurları için outlier özelliği taşımıştır.
Outlier detection in estimation blue, blup and variance components
Outlier detection for parameters in Henderson's Mixed Model Equation model was aimed in this study. For this purpose, 386 observations were used. Some observations were outlier for estimation of fixed effects but not for predictors of random effects. In addition, some observations that influential on fixed and random effects were not outlier for variance components. Only a few observation were influential either for fixed and random effects or for variance components.
