his paper proposes an alternative procedure for detecting outliers in meta-regression using the penalized maximum likelihood with smoothly clipped absolute deviation penalty function. The coordinate descent algorithm is ...
This article is considered to be the first to deal with the problem of outlier‐detection in multivariate circular data. The proposed algorithm is an extension of the Local Outlier Factor (LOF) method. Two different circular ...
Background: Cervical and breast cancers are leading causes of death among women. Although many current treatments used to treat these diseases, it is still rapidly spreading worldwide. Recently, triazole compounds have ...

Studying the association between random variables is an important subject in
statistical analysis. In the case of circular variables where their ranges are bounded; special
type of regression models are needed.
This ...
Indoor radon increases the health hazard due to long-term exposure. Most building materials of natural origin contain small amount of naturally occurring radioactive materials. The building materials of natural origin ...

+e aim of this article is to introduce a new definition for the Fourier transform. +is new definition will be considered as one of
the generalizations of the usual (classical) Fourier transform. We employ the new Katugampola ...

We focus our attention in this article on some recent results regarding Hardy-Hilbert's inequalities. We derive an
equivalent form using katugampola Fractional Calculus and introduce new analogs to some Hardy-Hilbert's ...
This paper aims to evaluate and map the groundwater quality in the
Gaza Strip by the means of geostatistical procedures including variograms,
Kriging and maps interpolation. Electrical Conductivity (EC) of water is ...
Circular data arise quite frequently in many natural and physical sciences. Standard
statistical techniques can't be used to analyze circular data due to the circular geometry of the
sample space. Circular data as any ...
Abuzaid, Ali; Saleh, Shokrya(STATISTICS, OPTIMIZATION AND INFORMATION COMPUTING, 2019-12-02)
Most of the commonly used linear regression variable selection techniques are affected in the presence of outliers
and high leverage points and often could produce misleading conclusions. This article proposes robust ...
Objective
We sought to evaluate the associations between thyroid hormones, metabolic parameters and anthropometric changes among Palestinian obese adult females.
Materials and methods
This case-control study included ...

This article considers the derivation of approximate distributions for two types of statistics that can be used in developing new tests of discordance in circular samples from the von Mises distribution. An alternative ...
This paper discusses the asymptotic covariance and outlier detection procedure in a linear functional relationship model for an extended circular model proposed by Caires and Wyatt. We derive the asymptotic covariance ...
Abuzaid, Ali; Hussin, AG; Mohamed ·, IB(Journal of Applied Probability and Statistics, 2009-05)
In this paper, a new definition of circular residuals based on circular distance is proposed. The property of the new residuals enables us to perform two tasks: the diagnostic checking on the assumption of linear circular ...
Abuzaid, Ali; Hussin, AG; Mohamed ·, IB(Journal of Statistical Computation and Simulation, 2013-02-01)
The investigation on the identification of outliers in linear regression models can be extended to those for circular regression case. In this paper, we propose a new numerical statistic called mean circular error to ...

Few studies have considered the modeling of a linear relationship between two circular variables or circular regression model. However, the problem of outlier detection in these models has not received enough consideration. ...
Abuzaid, Ali; Mohamed ·, IB; Hussin, AG(Communications in Statistics - Simulation and Computation, 2009-02-24)
In this article, we present an alternative test of discordancy in samples of univariate circular data. The new technique is based on the effect of existence of an outlier on the summation of circular distances of the point ...
