Abstract

Factor analysis is a frequently used multivariate analysis technique. The variance-covariance and correlation matrix play a fundamental role in factor analysis. Also principal components analysis provide useful information for factor analysis. In the presence of outlying observations in a data set may influence the factor anaysis results since they may influence the estimation of variance covariance matrix. In this study, robust measures used for the estimation of variance-covariance matrix is reviewed and a factor analysis problem, for a real life data set, is investigated using these estimated matrices.

Özet

Faktör analizi, yaygın kullanılan çok değişkenli bir analiz tekniğidir. Faktör analizinin temelinde varyans-kovaryans matrisi ve korelasyon matrisi hesaplanması aşaması bulunmaktadır. Asal bileşenler analizi, faktör analizi için çok faydalı sonuçlar ortaya çıkarmaktadır. Aykırı değerlerin bulunduğu veri setlerinde, varyans-kovaryans matrisi tahmini bulunurken aykırı değerlerden meydana gelen sapmalar, faktör analizini de etkilemektedir. Bu çalışmada varyans-kovaryans matrisi hesabında kullanılan robust ölçüler incelenmiş ve çok değişkenli bir veriye uygulanan faktör analizine katkısı araştırılmıştır.
