| Abstract | ||||
| The Multi-state cohort life table, which represents the non-absorbing state under study in the model that has two non-absorbing cases and one absorbing case, is defined as a decrement life table at which its inputs are calculated through the behavior of the case population of different cohorts and what is enrolled in each of successive age groups, but the decrement life table describes only the moving out state only from the population under study through successive age groups, and the life expectancy for this table does not take the re-entrance of any non-absorbing state under study through successive age groups. This study proposed a description for the entrance and re-entrance movement for the non-absorbing state under study by constructing tables which represents the behavior of the belongings of the non-absorbing state in each successive age group, each includes the probability of case enrolment in a degree under study plus the probabilities which describe the non-absorbing state from successive degrees in each age group. Also, this study proposed a modification for the life expectancy taken into consideration the re-entrance movement for the non-absorbing states under study through successive age groups. And to calculate the modified life expectancy at specific age in the non-absorbing state under study ; the average number of person years after this age in a non-absorbing state under study in this age, which transfer for this non-absorbing state to another non-absorbing state through any age group after the age under analysis –either returned back to the non-absorbing state under study in the same age group or next age groups - is added to the life expectancy calculated from the decrement life table. The above definition is being applied through constructing a cohort life table for the married case through the data presented by Wageeh (2003). | ||||
