SEM and Covariance Structure Analysis

"SEM (Structural Equation Modeling) and Covariance Structure Analysis is the same.

The name "Covariance Structure Analysis (CSA)" is popular. And in the Quality study, SEM (Scanning Electron Microscope) is also important. So I use "CSA" in this page.

Easily speaking, CSA is the mix of Path Analysis and Factor Analysis.

Pass Diagram and Structural Equation

SEM The figure is the simple case of the pass diagram and the structural equation.

Dealing with Error

Because real data include error(E), E is need to link the data and the equation.
