Uniform Minimum Variance Unbiased Estimator of Fractal Dimension

Recoletos 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 ...

An Uniformly Minimum Variance Unbiased Point Estimator Using Fuzzy Observations

Austrian 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 ...

Unbiased K-L estimator for the linear regression model [version 1; peer review: 2 approved, 1 approved with reservations]

F1000Research, 2021
Background: In the linear regression model, the ordinary least square (OLS) estimator performance drops when multicollinearity is present. According to the Gauss-Markov theorem, the estimator remains unbiased when there is multicollinearity, but the ...

Least square algorithm based on bias compensated principle for parameter estimation of canonical state space model

Measurement + Control, 2022
Due to the existence of system noise and unknown state variables, it is difficult to realize unbiased estimation with minimum variance for the parameter estimation of canonical state space model. This paper presents a new least squares estimator based on

Comparison of Some of Estimation methods of Stress-Strength Model: R = P(Y < X < Z)

مجلة بغداد للعلوم, 2021
In this study, the stress-strength model R = P(Y < X < Z)  is discussed as an important parts of reliability system by assuming that the random variables follow Invers Rayleigh Distribution. Some traditional estimation methods are used    to estimate the
