In this article we propose a new heteroskedastic consistent covariance matrix estimator, HC6, based on deviance measure. We have studied and compared the finite sample behavior of the new test and compared it with other this kind of estimators, HC1, HC3 a... see more

The paper considers a family of probability distribution depending on a parameter. The goal is to derive the generalized versions of Rao-Cramer, Bhattacharyya inequalities for the weighted covariance matrix and of the Kullback inequality for the weighted ... see more

A novel adaptive threshold spectrum sensing technique based on the covariance matrix of received signal samples is proposed. The adaptive threshold in terms of signal to noise ratio (SNR) and spectrum utilisation ratio of primary user is derived. It consi... see more

This paper describes the analytical expression of the attitude covariance matrix for the QUESTand TRIAD methods in an individual case. Influence of measurement model parameters on the accuracy ofattitude determination via the methods method is analyzed. A... see more

Article Details: Received: 2020-10-02 | Accepted: 2020-11-18 | Available online: 2021-06-30 https://doi.org/10.15414/afz.2021.24.02.110-116 Genetic diversity of selected 21 colombo lemon (Colombo limon L.) genotypes were evaluated through multivariat... see more

This paper establishes a novel reliability assessment method for industrial control system (ICS). Firstly, the qualitative and quantitative information were integrated by evidential reasoning(ER) rule. Then, an ICS reliability assessment model was constru... see more

The aim of this study was to estimate the reliability coefficients of the tests prepared by faculty members in the preparatory year courses for both males and females at the University of Tabuk, using the Raju formula based on the predetermined fixed weig... see more

The article describes an implementation of the negative log-likelihood function in the determination of uncorrelated noise standard deviation together with the parameters of spherical signal covariance model in least squares collocation (LSC) of gravity a... see more

We summarize properties of the spatial sign covariance matrix and especially consider the relationship between its eigenvalues and those of the shape matrix of an elliptical distribution. The explicit relationship known in the bivariate case was used to c... see more
