متن کاملBias and MSE Analysis of the IV Estimator Under Weak Identification with Application to Bias Correction∗
We provide results on properties of the IV estimator in the presence of weak instruments, beginning with the derivation of analytical formulae for the asymptotic bias (ABIAS) and mean squared error (AMSE). We also obtain approximations for the ABIAS and AMSE formulae based on an asymptotic scheme; which, loosely speaking, requires the expectation of the first stage F-statistic to converge to a ...
متن کاملAnalysis of Transient Flow in the Case of Secondary Injection for Transient Vector Control (RESEARCH NOTE)
The purpose of this paper is to analyze the flow field structure in transient state and performance of secondary injection system for thrust vectoring in divergent section of a two-dimensional nozzle. Secondary injection for thrust vectoring in a two-dimensional nozzle is studied by solving three-dimensional Reynolds-averaged equations by means of fluent solver. Spalart-allmaras model was used ...
متن کاملBias Correction in Group Sequential Analysis with Correlated Data
This paper focuses on the bias of the group sequential estimate of treatment effect for correlated data using the generalized estimating equation (GEE) method and the Lan and DeMets alpha-spending function. Linear and logistic regressions are used to examine (a) the magnitude of the bias of a sequential estimate with correlated data; (b) the influence of the true correlation structure on bias. ...
متن کاملPractice of Epidemiology Robust Estimation for Secondary Trait Association in Case-Control Genetic Studies
Secondary trait genetic association provides insight into the genetic architecture of disease etiology but requires caution in estimation. Ignoring case-control sampling may introduce bias into secondary trait association. In this paper, we compare the efficiency and robustness of various inverse probability weighted (IPW) estimators andmaximum likelihood (ML) estimators. ML methods have been p...
