The Use of Cross-Sectional and Longitudinal Weights in Korean Health Panel Survey |Biomedgrid

In household panel surveys, the same households and individuals are interviewed at multiple time points and then information is obtained from them. Panel studies have considerable analytical advantages over one-time surveys such as analysis of gross change, analysis of unit-level change, analysis of time related characteristics of events and identifying causality [1,2]. However, panel surveys often suffer from a high degree of panel attrition between waves, where panel attrition means the continued loss of respondents from the original sample due to mortality, migration between waves and survey non-response [2,3].
