Burada hedef, birimleri gerçek sınıfına minimum hatayla atamaktır.Lineer Diskriminant Analizi (LDA), veri kümesinde diğer gözlemlerden farklıhareket eden ve aykırı gözlem olarak adlandırılan gözlemlerin varlığındadayanıklı bir yöntem değildir ve güvenilir sonuçlar vermeyebilir. Böyledurumlarda, klasik LDA’nın dayanıklı versiyonlarının kullanımının gerekliliğiüzerine literatürde birçok çalışmaya rastlamak mümkündür. Bu çalışmada,jackknife yeniden örnekleme yaklaşımı, minimum kovaryans determinant (MKD) veLDA yönteminin bir kombinasyonu ile LDA’nın yeni bir dayanıklı versiyonu eldeedilmiştir. Önerilen bu yeni yaklaşımile Croux ve Dehon (2001) tarafından önerilen (Yöntem-1), Hawkins ve McLachlan(1997) tarafından önerilen (Yöntem-2) yaklaşımların aykırı gözlem oranındaki değişimleregöre nasıl etkilendiği yapay veri uygulaması ve benzetim çalışması üzerindendeğerlendirilmektedir. Elde edilen bulgular ışığında, önerilen yaklaşımın diğeriki yaklaşıma göre, veri kümesinde aykırı gözlemlerin varlığında performansınınbazı durumlarda daha iyi, bazı durumlarda ise en az onlar kadar iyi olduğugörülmektedir.</p></abstract>
