Fixed-effects partially linear regression models are useful tools to analyze data from economic, genetic and other fields. In this paper, we consider estimation and inference procedures when some of the covariates are measured with errors. The previously proposed estimati...
This work studies outlier detection and robust estimation with data that are naturally distributed into groups and which follow approximately a linear regression model with fixed group effects. For this, several methods are considered. First, the robust fitting method of Pe卤a and Yohai [A fast ...
“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...

Section 2 reviews the distribution theory necessary for Bayesian analysis of processes which are of the normal, linear fixed effects model type and presents a method of deriving Bayesian credibility intervals based on this distribution theory. Section 3 demonstrates the application of these methods to ...
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。

Unfortunately, this negative binomial model and its conditional likelihood does not really fit the bill as a fixed-effects method. The basic problem is that the θ i parameters that are conditioned out of the likelihood function do not correspond to different intercepts in the loglinear decomp...
Error using classreg.regr.lmeutils.StandardLinearLikeMixedModel/validateInputs (line 229) Fixed Effects design matrix X must be of full column rank. I don't understand why this is happening -- and probably this shows that I have a pretty big misunderstandi...
[1][2][3] Often the same structure of model, which is usually a linear regression model, can be treated as any of the three types depending on the analyst's viewpoint, although there may be a natural choice in any given situation. In panel data analysis, the term fixed effects ...
