Rational Fixed Points for Linear Group Actions
Pietro Corvaja §1 Introduction. A general principle in the theory of diophantine equations asserts that if an equation admits " many " rational solutions, there should be a geometric reason explaining such abundance. We consider here a (multiplicative) semigroup of N ×N matrices with rational entries: we suppose that all of them admit rational eigenvalues and deduce the natural geometrical cons...
متن کاملHow Lfe Works
Here is a proof for the demeaning method used in lfe, and a description of the methods used for solving the residual equations. As well as a toy-example. This is a preliminary version of [3]. This method, formulated as the Gauss-Seidel algorithm, was noted in [4] without the author noticing it in the first version of this paper.
متن کاملWithin-group Estimators for Fixed Effects Quantile Models
This paper provides within-group estimators for fixed effects quantile models. We apply the quantile coupling transformation to well approximate fixed effects quantile models by fixed effects Gaussian models. Our estimators enjoy three advantages: (1) fixed effects are eliminated by within-group estimators, so that ours is computationally fast without involving the increasing Hessian matrix wit...
متن کاملDynamic Linear Panel Regression Models with Interactive Fixed Effects
In the last step we used Assumption ID(ii). Because E [ Tr (e′e) ∣∣∣λ0, f , w] is independent of β, λ, f , we find minimizing Q(β, λ, f) is equivalent to minimizing Q∗(β, λ, f).

متن کاملFixed effects testing in high-dimensional linear mixed models
Many scientific and engineering challenges – ranging from pharmacokinetic drug dosage allocation and personalized medicine to marketing mix (4Ps) recommendations – require an understanding of the unobserved heterogeneity in order to develop the best decision making-processes. In this paper, we develop a hypothesis test and the corresponding p-value for testing for the significance of the homoge...
