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).

This study is an attempt to examine the determinants of Vietnamese commercial bank profitability under the moderating role of bank size. It uses the balanced panel data of 25 Vietnamese commerical banks in the period 2009-2021 and applies several regression estimation techniques such as FEM, REM, FGLS and PCSE.

The study attempts to examine the economic, demographic, and development determinants of economic complexity by using annual data spanning from 1995 to 2019. The advanced panel quantile method is employed to estimate the long-run impacts of driving forces on economic complexity along with its distribution.

The implementation duration of road work is critical as it impacts both the cost and outcome of the project. The article examines the techniques used to determine the time required for the completion of road work projects. It explores the approach to estimating the duration of road work projects in low- and middle-income countries (LMICs) based on the ROCKS database created by the World Bank.

This paper estimated the degree of elasticity substitution of inputs, particularly young labor, older labor, and physical capital. The elasticity of input substitution was estimated using a nested constant elasticity of substitution (CES) production function and nonlinear regression analysis. Research data were obtained from the annual secondary data of government sources from 1990 to 2013. The findings indicated that the input substitutability of young and older labor was low. However, capital and labor could substitute for each other.

The panel vector auto regression model is estimated using three main variables related to with profitability, financial liquidity, and financial leverage for 94 manufacturing companies from 2000 to 2017 in Indonesia. The aim is to examine the impact of oil price shocks on the ROA (profitability), CR (financial liquidity), and DER (financial leverage). The impulse reaction function of samples reveals some remarkable results. First, the response of ROA, DER, and CR appears to be consistent in many ways. Second, either Brent oil or WTI oil gives the same result for these variables.

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.

A database consisting of 23 tripeptides was used to study the quantitative relationships between electric surface potential descriptors and antioxidant activity QESARs. The important structural descriptors SaaNH_acnt, SsOH_acnt, SaaN, SaaN_acnt, SsssCH, SaaaC, SsNH3p, SdO, SdO_acnt were selected for constructing the linear models QESARs with genetic algorithm. The best 4-variable linear model QESARlinear including the structural descriptors SaaN, SdO, SdO_acnt and SsOH_acnt was constructed. The quality QESARlinear was exhibited in statistical values R2 fitness of 97.

Unstructured modelling growth of Lactobacillus acidophilus as a function of the temperature: We present modelling software developed under MATLAB in which parameter estimations are obtained by using non-linear regression techniques. The different parameters appear in a set of non-linear algebraic and differential equations representing the model of the process. From experimental data obtained in discontinuous cultures a representative mathematical model (unstructured kinetic model) of the macroscopic behaviour of Lactobacillus acidophilus has been developed.

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.
