Development of Intelligent, Computerized Aids for the Specification of Casual Models from Large Data Bases

Abstract

An automated process for forming measurement models and structural equation models was developed using an experimental version of TETRAD 11. An evaluation function was developed to select the measurement models and the structural models for further consideration. Comparisons were made between developing the models in this way and using factor analysis to develop measurement models. We found TETRAD 11 useful in building sets of measurement models and in suggesting sets of possible structural models. A previously unstudied dataset with a sample size of 7625 was used for testing the process. We developed measurement i-models and structural equation models which satisfied our intuitive understanding and had a Chi-square goodness-of-fit p-value of 0. 77.
