چکیده
Submit Manuscript | http://medcraveonline.com on PTEs and Stein-type estimators for various linear models. In statistical inference, the use of prior information on other parameters in a statistical model, usually leads to improved inference on the parameter of interest. Prior information may he (i) known and deterministic which is then incorporated into the model in the form of constraints on the parameter space, leading to a restricted model, or (ii) uncertain and specified in the form of a prior distribution or a verified null hypothesis. In (ii), choosing certain restricted estimators may be justified when the prior information can be quantified i.e. comes with known confidence levels.

Shrinkage Preliminary Test Estimation under a Precautionary Loss Function with Applications on Records and Censored Ddata
Shrinkage preliminary test estimation in exponential distribution under a precautionary loss function is considered. The minimum risk-unbiased estimator is derived and some shrinkage preliminary test estimators are proposed. We apply our results on censored data and records. The relative efficiencies of proposed estimators with respect to the minimum ‎risk-unbiased‎&...
متن کاملPitman-Closeness of Preliminary Test and Some Classical Estimators Based on Records from Two-Parameter Exponential Distribution
In this paper, we study the performance of estimators of parametersof two-parameter exponential distribution based on upper records. The generalized likelihood ratio (GLR) test was used to generate preliminary test estimator (PTE) for both parameters. We have compared the proposed estimator with maximum likelihood (ML) and unbiased estimators (UE) under mean-squared error (MSE) and Pitman me...

متن کاملA James - Stein Type of Detour of U - Statistics
SUMMARY. For a vector of estimable parameters, a modified version of the James-Stein rule (incorporating the idea of preliminary test estimators) is utilized in formulating some estimators based on U-statistics and their jackknifed estimator of dispersion matrix. Asymptotic admissibility properties of the classical U-statistics, their preliminary test version and the proposed estimators are stu...
متن کاملPositive-Shrinkage and Pretest Estimation in Multiple Regression: A Monte Carlo Study with Applications
Consider a problem of predicting a response variable using a set of covariates in a linear regression model. If it is a priori known or suspected that a subset of the covariates do not significantly contribute to the overall fit of the model, a restricted model that excludes these covariates, may be sufficient. If, on the other hand, the subset provides useful information, shrinkage meth...
