Multivariate Force of Mortality: Applications in Mortality Analysis

We introduce bi-variate and multivariate force of mortality functions. The pattern of mortality in a population is one of the strong influencing factors in determining the life expectancies at various ages in the population. Considering univariate functions of age only to understand the human mortality data without associating with other variables could lead to incomplete analysis. The reasons behind declining forces of mortality globally could be studied using the proposed functions.
