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 ...

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。
Bugfixes: summarize option was using full sample instead of regression sample, fixed a recent bug that failed to detect when FEs were nested within clusters Mata: refactor Mata internals and add their description to help reghdfe_mata; clean up warning messages Poisson/PPML HDFE: extend Mata in...

average of 50 patients per, you might be OK. The standard alternative is conditional logistic regression, but that would make it difficult/impossible to get the benchmarking scores that you desire. The hybrid (between/within) method that I describe in my books might work well in this ...
