For instance, medical trials can use different dosage levels over the trial, or during a single spell, the marital status or unemployment rate can change. Time-varying covariates are generally more easily handled in discrete-time problems, as covariates are rarely continuously observed. There are two key issues that arise when treating the time-varying covariates as fixed. First, a misspecification treat arises if the entire history of the variable matters rather than the specific values it takes on at certain time periods.
