Modelling Covariances and Latent Variables Using EQS

A short, accessible workbook detailing how to make the best use of the EQS software, often used in psychological and behavioural research. It has numerous examples and should enable users of the software to develop their own models and aid them in the interpretation of their data.

This primer has been designed as a self-instructional text which serves to introduce the reader to both the principles of statistical modelling of covariance structures and to the use of the EQS software package. It is divided into three parts - the first covering the basic ideas and language of covariance structure modelling together with an introduction to the EQS package. The second section covers a wide variety of models suitable for cross-sectional and longitudinal data and the final section discusses a wide variety of practical problems. This book should be of interest to researchers in psychology, sociology and medicine who use the EQS software; applied and consultant statisticians.
