Different Approaches to Covariance Structure Analysis: a Comparison

Covariance structure analysis with respect to observable (indicator) variables, collected for the description of inobservable or latent variables, can yield hints concerning causal relationships with respect to the latent variables. Meanwhile, for this problem area, different model approaches and software packages exist. This paper describes and compares important developments and points out own research directions.An example for clarification of some of the aspects addressed and a mathematically oriented appendix are included.
