Abstract
AbstractCategories of data screening and cleaning issues are reviewed and discussed. Bivariate model‐free approaches, specialized model‐free regression techniques, together with order statistic‐based (OSB) approaches are illustrated and shown to be of particular value for a variety of data screening and cleaning applications. It is shown how a combination of curve estimation with OSB approaches can help screen a progression to AIDS data set.
