Grateful if your team could advise whether the WebPower or any other R package(s) may provide power analysis facilities using a Monte-Carlo approach for the fit indices (e.g., AIC, SRMR) of a given structural equation model. For example, Mplus provides Monte Carlo analysis outputs for the expected and observed distributions of the fit indices of a specified model. It will be great if you can point me to similar facilities/functionalities available via WebPower or other R packages that are free. (I understand the functions of WebPower like "wp.sem.chisq", "wp.sem.rmsea" provide power analysis for fit statistics/indices - I am specifically interested in the availability of the corresponding facilities using a Monte Carlo approach).
