Maximun entropy Leuven estimators and multicollinearity

Statistica, 2007
A novel class of estimators, called maximum entropy Leuven (MEL) estimators, is presented and its performance is illustrated by Monte Carlo experiments. These estimators are inspired by the theory of light.

Evolutionary dynamics of the chloroplast genome in Daphne (Thymelaeaceae): comparative analysis with related genera and insights into phylogenetics

FEBS Open Bio, EarlyView.
Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...

Comparison Study Between Two Ways Least Squares and Adaptive Regression In Regression linear model [PDF]

المجلة العراقية للعلوم الاحصائية, 2007
In this research, we use on ( ) and ( ) two criterions to compare between the estimators of Adaptive Regression model and the estimators of Ordinary and General Least Squares, we found that, Adaptive Regression estimator is the best by comparing with ...

Indirect Inference Estimation of Spatial Autoregressions

Econometrics, 2020
The ordinary least squares (OLS) estimator for spatial autoregressions may be consistent as pointed out by Lee (2002), provided that each spatial unit is influenced aggregately by a significant portion of the total units.

Predicting and Comparing the Subjective Health Experience of Older Cancer Survivors and Non‐Cancer Survivors: A Modeling Approach

Aging and Cancer, EarlyView.
This study underscores the significant influence of frailty and vitality on the subjective health experience of older cancer survivors with acceptance and control emerging as salient mediators. These findings affirm the conceptual and empirical robustness of the model highlighting its potential utility in shaping future interventions for older cancer ...

Robust continuum regression. [PDF]

Several applications of continuum regression (CR) to non-contaminated data have shown that a significant improvement in predictive power can be obtained compared to the three standard techniques which it encompasses (ordinary least squares (OLS ...

Feasible robust Liu estimator to combat outliers and multicollinearity effects in restricted semiparametric regression mode

AIMS Mathematics
Regression analysis frequently encounters two issues: multicollinearity among the explanatory variables, and the existence of outliers in the data set.

Instrumental Variable Interpretation of Cointegration with Inference Results for Fractional Cointegration [PDF]

, 2002
In this paper we propose an alternative characterization of the central notion of cointegration, exploiting the relationship between the autocovariance and the cross-covariance functions of the series.

Estimation linear non-elementary regression models using ordinary least squares

МОДЕЛИРОВАНИЕ, ОПТИМИЗАЦИЯ И ИНФОРМАЦИОННЫЕ ТЕХНОЛОГИИ, 2020
При построении регрессионных моделей проблема выбора структурной спецификации является первостепенной. На сегодняшний день таких спецификаций разработано великое множество. В данной работе приводится краткое описание следующих форм связи между переменными: линейная регрессия, линейно-элементарная регрессия, линейно-мультипликативная регрессия ...
