It is meant for those who are less familiar with SEM but interested in panel data analysis as well as those familiar with SEM but new to fixed-effects regression. It demonstrates the decomposition of observed variables into within- and between-unit variance components using latent variables and ...
within estimatorAn interaction in a fixed effects (FE) regression is usually specified by demeaning the product term. However, this strategy does not yield a genuine within estimator. Instead, an estimator is produced that reflects unit-level differences of interacted variables whose moderators vary ...

I suspect the answer is yes. I explored this with a simulation. The coefficient and standard error are identical in the first model (the fixed effects regression) and the second model (the model with mean centered predictor and random effects). The goal is to estimate the within-"person" ...
Fixed Effects Models (very important stuff)
Inpanel dataanalysis, the termfixed effects estimator(also known as thewithin estimator) is used to refer to anestimatorfor thecoefficientsin the regression model. If we assume fixed effects, we impose time independent effects for each entity that are possibly correlated with the regressors。
