In statistics, a fixed effects model is a statistical model in which the model parameters are fixed or non-random quantities. This is in contrast to random effects models and mixed models in which all or some of the model parameters are random variables. In many applications including econometrics and biostatistics a fixed effects model refers to a regression model in which the group means are fixed (non-random) as opposed to a random effects model in which the group mean… WebMay 28, 2024 · The fixed-effects estimators, whether -xtreg-, -xtlogit-, -xtpoisson-, etc. are purely estimating within-panel effects. If a panel exhibits no outcome variation, then it provides no information about how other variables affect within-panel outcomes. So it is not possible for any such estimator to provide information about singleton panels.
