Modelling mortality differentials by age
Šuléřová, Natálie ; Mazurová, Lucie (advisor) ; Cipra, Tomáš (referee)
This diploma thesis deals with sex-specific mortality modelling, that is modelling in two populations - female and male, with emphasis on models considering the inter- dependence between these populations. Four models were theoretically described in the thesis - independent Lee-Carter model, the common factor model, the augmented com- mon factor model and the credibility model. All models were then applied to real mortality data in the female and male population of the Czech Republic and compared with each other. Mortality rates for Czech females and males were predicted by selected models. Finally, the effect of including a common factor in mortality modelling was analyzed in comparison with independent modelling in both populations as the difference in a lia- bility value arising from selected life insurance products. 1
