Using and Interpreting Fixed Effects Models
Fixed effects (FE) have emerged as a ubiquitous and powerful tool for eliminating unwanted variation in observational accounting studies. Unwanted variation is plentiful in accounting research because we often use rich data to test precise hypotheses derived from abstract theories.
Fixed and random effects models: making an informed choice
This paper assesses the options available to researchers analysing multilevel (including longitudinal) data, with the aim of supporting good methodological decision-making. Given the confusion in the literature about the key properties of fixed and random effects (FE and RE) models, we present these models' capabilities and limitations. We also discuss the within-between RE model, sometimes ...
Let's Talk About Fixed Effects: Let's Talk About All the Good Things
Fixed effects (FE) methods for panel data (models with observation unit-specific fixed effects Footnote 1) are widely applied in sociology and provide several advantages over cross-sectional methods.This has been shown in different contributions (e.g., Allison 2009; Brüderl and Ludwig 2015) Footnote 2.However, among the community of applied researchers, some confusion and misconceptions ...

Using and Interpreting Fixed Effects Models by Ed deHaan :: SSRN
Abstract. Fixed effects are ubiquitous in financial economics studies, but many researchers have a limited understanding of how they function. This manuscript explains how fixed effects can eliminate omitted variable biases and affect standard errors, and discusses common pitfalls in using fixed effect regressions.

A basic introduction to fixed‐effect and random‐effects models for meta
There are two popular statistical models for meta-analysis, the fixed-effect model and the random-effects model. The fact that these two models employ similar sets of formulas to compute statistics, and sometimes yield similar estimates for the various parameters, may lead people to believe that the models are interchangeable.

We argue that in most research scenarios, a well-speciied RE model provides everything that FE provides and more, making it the superior method for most practitioners (see also Shor et al. 2007;

Fixed-Effect vs Random-Effects Models for Meta-Analysis: 3 Points to
Most meta-analyses are based on 1 of 2 statistical models, the fixed-effect model or the random-effects model. 1. Understand that the assumptions for each model are different. 1. The fixed-effect model assumes 1 true effect size underlies all the studies in the meta-analysis, thus the term "fixed effect". Any differences in observed effects ...
Estimation of fixed effects semiparametric single-index panel model
This paper is organized as follows. Section 2 constructs the fixed effects SPSIPM with nonseparable spatio-temporal correlated errors, and its PQML estimation procedure. Section 3 presents some regular conditions and large sample properties of the estimators. Section 4 introduces a bootstrap test method for the single-index function. Section 5 shows simulation results in finite sample cases.

[PDF] Fixed Effects vs. Random Effects Meta‐Analysis Models
Research conclusions in the social sciences are increasingly based on meta-analysis, making questions of the accuracy of meta-analysis critical to the integrity of the base of cumulative knowledge. Both fixed effects (FE) and random effects (RE) meta-analysis models have been used widely in published meta-analyses. This article shows that FE models typically manifest a substantial Type I bias ...

A General Panel Model With Random and Fixed Effects: a Structural
Fixed and random effects models for longitudinal data are common in sociology. Their primary advantage is that they control for time-invariant omitted variables. However, analysts face several issues when they employ these models. One is the uncertainty of whether to apply the fixed effects (FEM) versus the random effects (REM) models.

Study models how ketamine's molecular action leads to its effects on
This peptide has been found to have health-promoting effects, such as reducing inflammation, that last much longer than ketamine's effects on NMDA receptors. The research team proposes that the entrainment of these neurons under ketamine could increase the release of the beneficial peptide, as observed when these cells are stimulated in ...

Stable hovering of proximity quadrotor UAV in-ground effect via model
This paper addresses the challenge of achieving stable hovering of two proximate Quadrotor UAVs (QUAVs) under the influence of ground effect, which introduces complex rotor airflow interactions. The existing rotor in-ground effect (IGE) models fail to accurately capture the ground effect on QUAVs, particularly when dealing with the interaction between proximate vehicles. To overcome this ...
