Recently‎, ‎the beta regression model has been used in several fields of science to data the form rate or proportion‎. ‎In this paper‎, ‎we propose some novel and improved methods estimate parameters model‎. ‎We consider a sub-space on coefficients combine unrestricted restricted estimators then we present Stein-type preliminary estimators‎. develop expressions for proposed estimators' asymptot...

Abstract: The problem of estimating the centre of symmetry of an unknown periodic function observed in Gaussian white noise is considered. Using the penalized blockwise Stein method, a smoothing filter allowing to define the penalized profile likelihood is proposed. The estimator of the centre of symmetry is then the maximizer of this penalized profile likelihood. This estimator is shown to be ...

5.1. Stein’s theorem and the regression model. It was pointed out in Chapter 2, section 2.2, that if no a priori knowledge is specified concerning β, the criterion of minimization of a matrix-valued meansquare error is ill posed. Nevertheless, there are some cases in which the choice of a particular scalar-valued definition of mean-square error makes it possible to obtain estimators with lower ...

Mutual fund selection is a notoriously difficult task, because past performance poor predictor of future performance. We propose measure that incorporates simple idea: shrinkage, in the sense Bayes-James-Stein, should be applied to gross return parameters, but not fees, which are known. The proposed Shrinkage Adjusted Sharpe ratio (SAS) substantially improves prediction out-of-sample relative e...
