Research on interactions (XZ) and quadratics (XX) in theoretical model (hypothesis) tests using structural equation analysis (LISREL, EQS, AMOS, SIMPLIS, etc.) and real-world data. Topics include XZ and XX reliability and validity. In theory tests these are important because low reliability/validity in XZ or XX may mean that a significant interaction or quadratic will be NS or of opposite sign in its next model test. Other topics include estimating categorical (nominal) variables, and improving measures that are in serious trouble--ones with low Average Variance Extracted (AVE), or unacceptable model-to-data fit (i.e., only a 3-indicator specification fits the data, etc.)
