A new Liu-type estimator in a mixed Poisson regression model [PDF]

open access: yesScientific Reports
Mixed Poisson regression models (MPRMs) are widely used for analyzing overdispersed count data. However, the presence of multicollinearity among explanatory variables poses challenges when estimating regression coefficients using the maximum likelihood ...

A New Mixed Biased Estimator for Ill‐Conditioning Challenges in Linear Regression Model With Chemometrics Applications [PDF]

open access: yesAnalytical Science Advances
In linear regression models, the ordinary least squares (OLS) method is used to estimate the unknown regression coefficients. However, the OLS estimator may provide unreliable estimates in non‐orthogonal models.

A mixed distribution approach for low-flow frequency analysis – Part 2: Comparative assessment of a mixed probability vs. copula-based dependence framework [PDF]

open access: yesHydrology and Earth System Sciences, 2023
In climates with a warm and a cold season, low flows are generated by different processes, which violates the homogeneity assumption of extreme value statistics.

A new almost unbiased estimator in stochastic linear restriction model [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2011
In this paper, a new almost unbiased estimator is proposed under stochastic linear restrictions model as alternative to mixed estimator. The performance of the proposed estimator compared to mixed estimator is examined using the matrix mean squared ...

The Mixed Liu Estimator in Stochastic Restricted Linear Measurement Error Model

open access: yesJournal of Mathematics, 2021
Ghapani and Babdi [1] proposed a mixed Liu estimator in linear measurement error model with stochastic linear restrictions. In this article, we propose an alternative mixed Liu estimator in the linear measurement error model with stochastic linear ...

Estimation Curve of Mixed Spline Truncated and Fourier Series Estimator for Geographically Weighted Nonparametric Regression

open access: yesMathematics, 2022
Geographically Weighted Regression (GWR) is the development of multiple linear regression models used in spatial data. The assumption of spatial heterogeneity results in each location having different characteristics and allows the relationships between ...

Mixed Model-Based Hazard Estimation [PDF]

open access: yesJournal of Computational & Graphical Statistics, 2002
We propose a new method for estimation of the hazard function from a set of censored failure time data, with a view to extending the general approach to more complicated models. The approach is based on a mixed model representation of penalized spline hazard estimators.

On the mixed Kibria–Lukman estimator for the linear regression model

open access: yesScientific Reports, 2022
This paper considers a linear regression model with stochastic restrictions,we propose a new mixed Kibria–Lukman estimator by combining the mixed estimator and the Kibria–Lukman estimator.This new estimator is a general estimation, including OLS ...
