Integration of Path Models for Structural Equation Modeling by Use of Union Operation for Merging Multiple Viewpoints

This study describes a method for integration of multiple path models. Structural equation modeling (SEM) is useful for causality analysis. However, the result of SEM may lack reliability owing to the model being constructed upon subjective assumptions. To mitigate this condition, the integration of multiple path models by use of the union operation is proposed. Four integrations are performed in an experiment for each feature case and the method usability is discussed.
