Eliptik sözde-kopulalar ile esnek bağımlılık modellemesi

Year 2020, Volume: 13 Issue: 2, 61 - 77, 31.12.2020

Abstract

Finansal ve aktüeryal bağımlılık modellemesi çalışmalarında sıklıkla tercih edilen eliptik kopulalar, dinamik bağımlılık modellemesi elde etmek ve kuyruk bağımlılığı ile eliptik bağımlılığın modellenebilmesi gibi çeşitli nedenler ile düzenlenebilir. Düzenlenmiş sözde-kopula ile esnek bir bağımlılık modellemesi elde edilir. Bu çalışmada, düzenlenmiş sözde-kopula fonkiyonlarının düzenlemeden sonra da sözde-kopula fonksiyonu özelliğini koruduğu gösterilmiş ve bu fonksiyonların elde edilme aşamaları verilmiştir. Uygulama bölümünde, sözde-kopula fonksiyonlarının düzenlenmesinin etkinliği perspektif ve izohips eğrileri ile incelenmiş ve düzenlemenin sağladığı fayda, düzenlenmiş sözde-kopula regresyon modelleri yardımıyla gösterilmiştir.
