Estimator and regression estimator

This study seeks to comprehend the influencing factors on the economic growth of the pivotal economic region in the Southwest. The authors conducted research based on the dataset from four provinces and cities in the region during the period 2005-2022, employing panel data estimation methods such as OLS pooled regression, fixed effects (FEM), and random effects (REM).

The study applies quantitative method on non-balanced panel samples of Vietnamese listed firms which are extracted from the Thomson Reuters database and manually collected from companies’ annual reports. All the regressions are estimated by Generalized Least Squared (GLS) method to fix the heteroscedasticity problem and robusted by Generalized Method of Moment (GMM) for endogeneitity potential.

The estimation of the model parameters is performed by maximum likelihood method. We hope that the new distribution proposed here will serve as an alternative model to the other models which are available in the literature for modeling positive real data in many areas.

ESSAYS ON TOTAL FACTOR PRODUCTIVITY AND HUMAN CAPITAL In fact, I do not estimate separate regressions for each MSA, but the general effect is the same: Unreliability of the peer group measure produces an upward bias in the effect of choice on the peer group gradient, and therefore in the interaction coefficient 1 ϕ

Essays in Macroeconomics and the Economics of Higher Education In single-MSA regressions of test scores on student characteristics, the above arguments imply greater attenuation of the peer group coefficient in MSAs with less stratified schools. As choice is positively correlated with stratification, this produces a tendency toward larger estimated coefficients (i.e. less bias toward zero) in high-choice MSAs.

THE RELATIONSHIP OF CROSS-CULTURAL DIFFRECES TO THE VALUES OF INFORMATION SYSTEMS PROFESTIONAL WITHIN THE CONTEXT OF SYSTEMS DEVELOPMENT For each (δ , J) combination, I estimated a regression of μ j on x j analogous to those estimated from actual data in Section 1.5, pooling all 5,000 simulated markets and including a fixed effect for each. The resulting estimates of ( ) ( ) ( ) θ δ , J = cov x j ,μ j var x j are displayed in Figure 1.3. The trends identified in Figures 1.1 and 1.2 are again clear. First,...

1) Introduction The estimates of the regression parameters are influenced by a few extreme observations. The residual plot may let us pick out, which the individual data points are high or low. We may use the residual plot to find the outlier, which are inadequately captured by the regression model itself.
