Abstract:
In the presence of continuous covariates, standard capture-recapture
methods assume either that the registrations operate independently at
the individual level or that the covariates can be stratified and
log-linear models fitted, permitting the modelling of dependence between
data sources. This article introduces an approach where direct
dependence between registrations is modelled leaving the continuous
covariates in their measurement scale. Simulations show that not
accounting for possible dependence between registrations results in
biased estimation of both the population size and standard error.
The proposed method is applied to Dutch neural tube defect registration
data.
