Title: | Effect of Dropouts in a Longitudinal Study: An Application of a Repeated Ordinal Model | Authors: | LESAFFRE, Emmanuel MOLENBERGHS, Geert Dewulf, Lode |
Issue Date: | 1996 | Source: | Statistics in Medicine, 15(11). p. 1123-1141 | Abstract: | An analysis is presented of a longitudinal study of fluvoxamine, an antidepressant drug, with ordinal responses, regressed on a combination of discrete and continuous covariates and with a substantial proportion of dropouts. Classical methods, such as weighted least squares (SAS procedure CATMOD) and logistic regression, are not suitable for the analysis of such data. Instead, we illustrate how a recently introduced model can be used to solve most of the problems posed. The method is likelihood-based and is an extension of the bivariate Dale model to an arbitrary number of outcomes. The method is suitable for several types of designs commonly employed in clinical trials. | Document URI: | http://hdl.handle.net/1942/317 | ISSN: | 0277-6715 | e-ISSN: | 1097-0258 | DOI: | 10.1002/(SICI)1097-0258(19960615)15:11<1123::AID-SIM228>3.0.CO;2-L | Rights: | (C) 1996 by John Wiley & Sons, Ltd. | Type: | Journal Contribution |
