title: A statistical analysis of birth-order effects with application to data on pyloric stenosis.
abstract: A method is presented for correcting incomplete data for birth-order analysis and variations in the ascertained incidence of affected individuals are allowed. The statistical analysis involves application of a test developed by Wilcoxon, Mann and Whitney, and Haldane and Smith. Examples are detailed for data correction, and the analysis of data for pyloric stenosis is discussed.
