symSEM-package {symSEM} | R Documentation |
A collection of functions for symbolic computation using 'caracas' package for structural equation models and other statistical analyses. Among its features is the ability to calculate the model-implied covariance (and correlation) matrix and the sampling covariance matrix of variable functions using the delta method.
As 'caracas' uses 'SymPy" in the backend. Reserved words in SymP, such as"lambda" and "I" are converted to some random strings first. These random strings are converted back to R.
