Median Radial Function: A Robust, Covariance-Free Framework and Applications
Elsayed Elamir
A median-radius framework for assessing centrality in multivariate data using median distances is proposed. Based on the proposed framework, a scale-invariant measure of radial con…
Exploring Multivariate Data Using Median Absolute Deviation Depth
Elsayed Elamir
We propose and analyze the moving median absolute deviation (MMAD) as a robust depth construction based on the median absolute distance functional with particular emphasis on its l…
Depth-Based Vector Median Absolute Deviation Moments for Robust Multivariate Shape Analysis
Elsayed Elamir
Classical multivariate shape analysis relies on covariance-standardized moments, such as Mardia skewness and kurtosis, which are sensitive to outliers and require finite moments. T…
A Robust Moment System Based on Absolute Deviations and Quantile Slicing
Elsayed Elamir
This study develops two robust, quantile-sliced moment systems, mean and median absolute deviation (MAD and MedAD moments), to serve as foundational tools in parametric modeling, s…
A Percentile-Focused Regression Method for Applied Data with Irregular Error Structures
Elsayed Elamir
Irregular errors such as heteroscedasticity and nonnormality remain major challenges in linear modeling. These issues often lead to biased inference and unreliable measures of unce…
The Role of Mean Absolute Deviation Function in Obtaining Smooth Estimation for Distribution and Density Functions: Beta Regression Approach
Elsayed A. H. Elamir
Smooth Estimation of probability density and distribution functions from its sample is an attractive and an important problem that has applications in several fields such as, busin…
On Uses of Mean Absolute Deviation: Shape Exploring and Distribution Function Estimation
Elsayed A. H. Elamir
Mean absolute deviation function is used to explore the pattern and the distribution of the data graphically to enable analysts gaining greater understanding of raw data and to fos…
On Uses of Van der Waerden Test: A Graphical Approach
Elsayed Elamir
Although several nonparametric tests are available for testing population identical distributions or equal means in multiple groups problem, the Van der Waerden test has asymptotic…
A Graphical Approach for Friedman Test: Moments Approach
Elsayed A. H. Elamir
Friedman test is a nonparametric method that proposed for analyzing data from a randomized complete block design as a robust alternative to parametric method and widely applied in…
Simultaneous test for Means: An Unblind Way to the F-test in One-way Analysis of Variance
Elsayed A. H. Elamir
After rejecting the null hypothesis in the analysis of variance, the next step is to make the pairwise comparisons to find out differences in means. The purpose of this paper is th…
