Bias corrected generalized method of moments and generalized quasi-likelihood inferences in linear models for panel data with measurement error

چکیده
For the estimation of the parameters involved in a linear dynamic mixed model for panel data, it has been shown recently by Rao, Sutradhar, and Pandit (2012, Brazilian J. of Probability and Statistics, Vol. 26, 167–177) that the so-called generalized quasi-likelihood (GQL) approach produces more efficient regression estimates as compared to the generalized method of moments (GMM) approach. These standard approaches, however, produce biased and hence inconsistent regression estimates when the time dependent covariates in such panel data models are subject to measurement errors. In this paper, we develop a bias corrected GQL (BCGQL) estimation approach and demonstrate that the BCGQL approach produces more efficient regression estimates than the BCGMM approach.

Detection of Outliers and Influential Observations in Linear Ridge Measurement Error Models with Stochastic Linear Restrictions
The aim of this paper is to propose some diagnostic methods in linear ridge measurement error models with stochastic linear restrictions using the corrected likelihood. Based on the bias-corrected estimation of model parameters, diagnostic measures are developed to identify outlying and influential observations. In addition, we derive the corrected score test statistic for outliers detection ba...
متن کاملEstimation of Parameters for an Extended Generalized Half Logistic Distribution Based on Complete and Censored Data
This paper considers an Extended Generalized Half Logistic distribution. We derive some properties of this distribution and then we discuss estimation of the distribution parameters by the methods of moments, maximum likelihood and the new method of minimum spacing distance estimator based on complete data. Also, maximum likelihood equations for estimating the parameters based on Type-I and Typ...
متن کاملHigher Order Properties of Gmm and Generalized Empirical Likelihood Estimators
In an effort to improve the small sample properties of generalized method of moments (GMM) estimators, a number of alternative estimators have been suggested. These include empirical likelihood (EL), continuous updating, and exponential tilting estimators. We show that these estimators share a common structure, being members of a class of generalized empirical likelihood (GEL) estimators. We us...
