TITLE:             "Modeling Growth and Decline with Structural
                   Equations"


                       ABSTRACT

    This seminar reviews some of the history leading up to current efforts to
model growth and decline.  The growth curve approach advocated by Rogosa
et. al (1982) is compared with classic autoregressive models (e.g., Kessler and
Greenberg 1981).  Structural equation approaches to modeling growth and
decline using LISREL and EQs are compared with a popular alternative that
uses hierarchical linear models (HLM).  Examples are from the Iowa Youth
and Family Project and from the Iowa Single Parent Project.
