Abstract

Statistical classification analysis has been widely used in many fields. In this article, we applied and compared three different classification procedures: Logistic regression, Fisher''s linear discriminant function and the second order Bahadur representation to two datasets from two surveys on asthma among healthcare professional in Texas. The first dataset contained 102 subjects and the second dataset 2963. The concordance of the classification from the three statistical procedures with possible asthma identified by physician and airway responsiveness to methacholine challenge was assessed through Cohen's κ statistic via a series of 2 × 2 contingency tables.
