N, total number of years due to the corresponding effect in each age group.
Direct effect, years of life gained in the age group x, x+n owing to the mortality changes in the group itself.
Indirect effect, years of life gained after the age x+n because of an increased number of survivors (as a result of the mortality changes of the age group x, x+n, assuming that the mortality of the older age groups does not change).
Interaction, years of life gained because of the supplementary survivors at age x+n as a consequence of mortality changes between x and x+n, taking into account that the mortality in the higher age groups also changes.
