Abstract

In medical science, in investigating the
survival data of epidemic diseases and chronic diseases and determining the
factors which affects these diseases, Cox regression model for survival
analysis has gained widespread attention. In this paper, Cox regression model is
presented and using this model risk factors affecting relapse  of  lung
cancer is determined.

Keywords

Cox Regresyon Modeli ve Akciğer Kanseri Verileri İle Bir Uygulama

Abstract

Tıpta, salgın hastalıklara ve kronik hastalıklara ilişkin verilerin incelenmesi ve bu hastalıkları etkileyen faktörlerin saptanması için yaşam çözümlemesinde Cox regresyon modeli oldukça önemlidir. Bu çalışmada, Cox regresyon modeli tanıtılmış ve bu model kullanılarak akciğer kanserinde nüksü etkileyen risk faktörleri belirlenmiştir

Keywords
