Likelihood Ratio Test P-Values for Structural Equation Models
Computes likelihood ratio test (LRT) p-values
for free parameters in a structural equation model.
Currently supports models fitted by the 'lavaan' package by

semlrtp: Likelihood Ratio Test p-Values for Structural Equation Models 
This package is used for computing LRT p-values for free parameters in structural equation model using likelihood ratio test (LRT). As demonstrated in the Get-Started article, the LRT p-value has some advantages over the usual p-values reported in SEM program.
However, it is not easy to compute them because each p-value requires fitting one additional model. We developed this package to make this process simple and automatic such that it is practical to use LRT p-values in most commonly interpreted parameters.
See the Get-Started article for a quick demonstration on how to use this package.
