Abstract:
Anticipatory covariates, such as educational level and social class, are variables whose values refer to what is attained at the time of survey. Such variables are common in retrospective surveys and are often used as explanatory variables in investigations of behavior, like marriage or divorce, in life segments that have occurred before the survey. This causes problems because the procedure does not follow the temporal order of events. In this study, we propose a dynamic Bayesian modelling approach that allows effects of the anticipatory covariate to vary over time. The issues are illustrated with data on the effects of anticipatory educational level on divorce risks among Swedish men. Results show that failure to adjust for the anticipatory nature of education leads to overestimation of the relative risks of divorce among those with higher education (relative to the baseline group). More importantly, the degree of overestimation varies across duration of marriage.
