There are many approaches to nonlinear SEM (structural equation modeling) but it seems that a rather straightforward approach using Isserlis’ theorem has not yet been investigated although it allows the direct extension of the standard linear approach to nonlinear linear SEM. The reason may be that this method requires some symbolic calculations done at runtime. This paper describes the class of appropriate models and outlines the algorithm that calculates the covariance matrix and higher… Expand
