Query: Estimation of marriage incidence rates by combining two cross-sectional
  retrospective designs: Event history analysis of two dependent processes   The aim of this work is to develop methods for studying the determinants of
marriage incidence using marriage histories collected under two different types
of retrospective cross-sectional study designs. These designs are: sampling of
ever married women before the cross-section, a prevalent cohort, and sampling
of women irrespective of marital status, a general cross-sectional cohort.
While retrospective histories from a prevalent cohort do not identify incidence
rates without parametric modelling assumptions, the rates can be identified
when combined with data from a general cohort. Moreover, education, a strong
endogenous covariate, and marriage processes are correlated. Hence, they need
to be modelled jointly in order to estimate the marriage incidence. For this
purpose, we specify a multi-state model and propose a likelihood-based
estimation method. We outline the assumptions under which a likelihood
expression involving only marriage incidence parameters can be derived. This is
of particular interest when either retrospective education histories are not
available or related parameters are not of interest. Our simulation results
confirm the gain in efficiency by combining data from the two designs, while
demonstrating how the parameter estimates are affected by violations of the
assumptions used in deriving the simplified likelihood expressions. Two Indian
National Family Health Surveys are used as motivation for the methodological
development and to demonstrate the application of the methods.
