...dealt with by using bootstrap estimations. But, I was wondering how the fit indexes in the SEM package were estimated when the observed variables are categorical (ordinal or/and binary) and when one is using polychoric correlation (hetcor in polycor package) in combination with ML. Does SEM use the Satorra-Bentler rescaled Chi-square for instance? I look in previous posts but couldn't find what i am looking for (hope i looked well enough!).

...express their models in a compact, elegant and useR-friendly way - lavaan is robust and reliable: there are no convergence problems and numerical results are very close (if not identical) to the commercial package Mplus - many different estimators are available: ML, GLS, WLS, robust ML using Satorra-Bentler corrections, and FIML for data with missing values - full support for meanstructures and multiple groups - user friendly output including standardized solutions, fit measures, modification indices and more To get a first impression of how the 'lavaan model syntax' looks like, b...

I am a new user of the function sem in package sem and lavaan for structural equation modeling 1. I don?t know what is the difference between this function and CFA function, I know that cfa for confirmatory analysis but I don?t know what is the difference between confirmatory analysis and structural equation modeling in the package lavaan. 2. I have data that I want to analyse but I have some
