Query: A General Age-Specific Mortality Model with An Example Indexed by Child
  or Child/Adult Mortality   BACKGROUND. The majority of countries in Africa and nearly one third of all
countries require mortality models to infer complete age schedules of
mortality, required for population estimates, projections/forecasts and many
other tasks in demography and epidemiology. Models that relate child mortality
to mortality at other ages are important because all countries have measures of
child mortality.
  OBJECTIVE. 1) Design a general model for age-specific mortality that provides
a standard way to relate covariates to age-specific mortality. 2) Calibrate
that model using the relationship between child or child/adult mortality and
mortality at other ages. 3) Validate the calibrated model and compare its
performance to existing models.
  METHODS. A general, parametrizable component model of mortality is designed
using the singular value decomposition (SVD-Comp) and calibrated to the
relationship between child or child/adult mortality and mortality at other ages
in the observed mortality schedules of the Human Mortality Database. Cross
validation is used to validate the model, and the predictive performance of the
model is compared to that of the Log-Quad model, designed to do the same thing.
  RESULTS. Prediction and cross validation tests indicate that the child
mortality-calibrated SVD-Comp is able to accurately represent the observed
mortality schedules in the Human Mortality Database, is robust to the selection
of mortality schedules used to calibrate it, and performs better than the
Log-Quad Model.
  CONCLUSIONS. The child mortality-calibrated SVD-Comp is a useful tool that
can be used where child mortality is available but mortality at other ages is
unknown. Together with earlier work on an HIV prevalence-calibrated version of
SVD-Comp, this work suggests that this approach is truly general and could be
used to develop a wide range of additional useful models.
