In this article, I show that when the number of fixed effects is large, the computational speed is massively increased by using xtreg rather than regress to fit the unconditional quantile regression models. I also introduce the xtrifreg command, which should be considered a supplement to rifreg...
fixed effectsinteractionquadratic termspolynomialswithin 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 ...
This book demonstrates how to estimate and interpret fixed-effects models in a variety of different modeling contexts: linear models, logistic models, Poisson models, Cox regression models, and structural equation models. Both advantages and disadvantages of fixed-effects models will be considered, ...
The fixed-effects Poisson regression model allows for unrestricted heterogeneity across individuals but, for a given individual, there is still the restriction that the mean of each count must equal its variance: 5 it it it y y E µ = = ) var( ) ( (3) In many data sets, howev...
“回归”的思想其实渗透着“舍得”的理念:我们通过舍弃那些“随机部分”的误差(residual variance),获得了我们想要的“固定部分”的参数(regression coefficients)。 2 / 多层线性模型(HLM) 如果说回归是众多统计方法的本质,那么多层线性模型(Hierarchical Linear Model, HLM)就可以视为众多统计方法的“幕后主谋”——回...
