Connections between A.K. Romney's analyses of endogamy and other developments in log-linear models and network analysis

This paper examines contributions of A.K. Romney and associates to analyses of endogamy, and discusses the more general themes explored in these endogamy studies. The techniques used in these papers are relevant to many types of analysis of contingency tables, and to other settings such as social mobility. Some of these connections are explored here, all with a view to the importance of the margins of the table for different kinds of analysis. In particular, the paper discusses descriptive and analytical uses of classical iterative proportional fitting (IPF), some specific log-linear models, and the margins of sociomatrices. The paper also includes analyses of example data. (C) 2002 Elsevier Science B.V. All rights reserved.
