Estimation of the number of cases of meningococcical disease in Barcelona by means capture-recapture methodology

This study is aimed at estimating the number of cases fo meningococcical disease that appeared in Barcelona between the years 1993 and 1994. We develop long-linear models for capture-recapture methods when there are more than two incomplete lists. The capture-recapture model that we used allows for the sources being not independent and for heterogeneity in the probability of being in a source.
