Uniform Minimum Variance Unbiased Estimator of Fractal Dimension

open access: diamondRecoletos Multidisciplinary Research Journal, 2021
The paper introduced the concept of a fractal distribution using a power-law distribution. It proceeds to determining the relationship between fractal and exponential distribution using a logarithmic transformation of a fractal random variable which ...

The construction of the uniformly minimum variance unbiased estimator [PDF]

open access: bronzeTsukuba Journal of Mathematics, 2010
For a one-parameter exponential family of distributions, a method to find the uniformly minimum variance unbiased (UMVU) estimator based on the complete sufficient statistic is given in Jani and Dave [1] by change of the expression of the unbiasedness ...

An Uniformly Minimum Variance Unbiased Point Estimator Using Fuzzy Observations

open access: diamondAustrian Journal of Statistics, 2016
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 ~X1,...,~Xn  is ...

Asymptotic Efficiency of Minimum Variance Unbiased Estimators

open access: hybridThe Annals of Statistics, 1977
Consider a regular $p$-dimensional exponential family such that either the distributions are concentrated on a lattice or they have a component whose $k$-fold convolution has a bounded density with respect to Lebesgue measure.

The Construction of Uniformly Minimum Variance Unbiased Estimators for Exponential Distributions [PDF]

open access: goldThe Annals of Mathematical Statistics, 1970
1. Summary and Introduction. Consider a sample (Xl, X2 * , XN) from a population with a distribution function F0(x), (0eK2) for which a complete sufficient statistic, s(x), exists.

An Optimal Channel Estimation Scheme for Intelligent Reflecting Surfaces based on a Minimum Variance Unbiased Estimator [PDF]

open access: greenIEEE International Conference on Acoustics, Speech, and Signal Processing, 2019
In a wireless system with Intelligent Reflective Surfaces (IRS) containing many passive elements, we consider the problem of channel estimation. All the links from the transmitter to the receiver via each IRS elements (or groups) are estimated.

An unbiased estimator with prior information

open access: yesArab Journal of Basic and Applied Sciences, 2020
The ordinary least square (OLS) estimator suffers a breakdown in the presence of multicollinearity. The estimator is still unbiased but possesses a significant variance.
