An Unbiased Two-Parameter Estimation with Prior Information in Linear Regression Model
We introduce an unbiased two-parameter estimator based on prior information and two-parameter estimator proposed by Özkale and Kaçıranlar, 2007. Then we discuss its properties and our results show that the new estimator is better than the two-parameter estimator, the ordinary least squares estimator, and explain the almost unbiased two-parameter estimator which is proposed by Wu and Yang, 2013....
متن کاملThe Minimum Variance Unbiased Estimator
This module motivates and introduces the minimum variance unbiased estimator (MVUE). This is the primary criterion in the classical (frequentist) approach to parameter estimation. We introduce the concepts of mean squared error (MSE), variance, bias, unbiased estimators, and the bias-variance decomposition of the MSE. The Minimum Variance Unbiased Estimator 1 In Search of a Useful Criterion In ...
متن کاملAn (almost) unbiased estimator for the S-Gini index∗
This note provides an unbiased estimator for the absolute S-Gini and an almost unbiased estimator for the relative S-Gini for integer parameter values. Simulations indicate that these estimators perform considerably better then the usual estimators, especially for small sample sizes. 1 The absolute and relative S-gini indices Assume that income is distributed according to a continuous and diffe...
متن کاملAn Uniformly Minimum Variance Unbiased Point Estimator Using Fuzzy Observations
This paper proposes a new method for uniformly minimum variance unbiased fuzzy point estimation. For this purpose we make use of a uniformly minimum variance unbiased estimator and we develop this new method for a fuzzy random sample X̃1, . . . , X̃n is induced by X1, . . . , Xn on the same probability space. Zusammenfassung: In diesem Aufsatz schlagen wir eine neue Methode vor, um einen unverzer...
متن کاملAn Unbiased Scattering Function Estimator for Fast Time-varying Channels*
E{S[m, I ] S*[m', l ' ] } = C[m, I ] 6[m m'] 6 [ l 1 ' 1 , (1) We propose an unbiased, computationally efficient estimator of the scattering function that is specifically suited to underspread WSSUS channels. The novel estimator allows for nonideal sounding signals, fast time-variation, and on-line where E denotes expectation, s[m, I1 = czzi h[n, m1 e-j21rln" is the (delay-Doppler) spreading fu...
