Abstract
Multinomial logit discrete-choice models are now being used more frequently in sociological research, but often without appropriate attention to the central role played by the independence of irrelevant alternatives (IIA) property. In this article, three tests of the IIA property are discussed and then how to apply them is illustrated, using a data set previously analyzed by Hoffman and Duncan. The IIA tests decisively reject the IIA property in the single/welfare/remarriage choice model.Keywords
