Duration distributions can be estimated from data recorded during followup of panel members in longitudinal surveys, but adjustments for the sample design, population structure and losses to followup are typically required. We provided weighted Kaplan-Meier estimates that allow for these features and, in particular, adjust for dependent loss to followup through the use of inverse probability of censoring weights.enDropoutInverse probability weightsLoss to followupSpell durationsSurvival distributionsWeighted Kaplan-Meier estimatesArticle
