Sample Design and Estimation of Parameters of Half Logistic Distribution Using Generalized Ranked-Set Sampling

open access: yesJournal of Statistical Theory and Applications (JSTA), 2020
The ranked-set sampling technique has been generalized so that a more efficient estimator may be obtained. This technique allows more than one unit from each set to be quantified.

n effective treatment of adding-up restrictions in the inference of a general linear model

open access: yesAIMS Mathematics, 2023
This article offers a general procedure of carrying out estimation and inference under a linear statistical model $ {\bf y} = {\bf X} \pmb{\beta} + \pmb{\varepsilon} $ with an adding-up restriction $ {\bf A} {\bf y} = {\bf b} $ to the observed random ...

Location Of Objects with a High Degree of Inner Precision

open access: yesSlovak Journal of Civil Engineering, 2014
Let us have two coordinate systems in a plane. In the first one (e.g. JTSK) the accuracy of the coordinate estimators is signicantly lower than the accuracy in the other system (the inner system of an object).

Upper bounds for the Euclidean distances between the BLUPs

open access: yesSpecial Matrices, 2018
In this article we consider the general linear model {y, X ß, V} where y is the observable random vector with expectation X ß and covariance matrix V. Our interest is on predicting the unobservable random vector y* which comes from y* = X* ß + ƹ* where ...

Combination of Fuzzy Logic and Kriging Technique Under Uncertainty for Spatial Data Prediction [PDF]

open access: yesمجلة التربية والعلم, 2022
This paper deals with the spatial prediction in Geostatistics. This paper depend on interpellation methods of spatial statistic (ordinary kriging technique) to combination with fuzzy logic under uncertainty for spatial data prediction. This work includes

Estimation of the location parameter of distributions with known coefficient of variation by record values

open access: yesStatistica, 2014
In this article, we derived the Best Linear Unbiased Estimator (BLUE) of the location parameter of certain distributions with known coefficient of variation by record values. Efficiency comparisons are also made on the proposed estimator with some of the

Hammerstein system with a stochastic input of arbitrary/unknown autocorrelation: Identification of the dynamic linear subsystem

open access: yesIET Signal Processing, 2021
For a Hammerstein system subject to a stochastic input that is spectrally coloured, this study is first in the open literature (to the present authors' best knowledge) to estimate its linear dynamic subsystem.

Best Linear Unbiased Estimators for Repeated Surveys [PDF]

open access: yesJournal of the Royal Statistical Society Series B: Statistical Methodology, 1980
Summary Recent work on the problem of obtaining best linear unbiased estimators from a sample survey which is repeated on several occasions has centred on the effects of extending the model assumptions to allow for stochastic variation in the parameters being estimated.
