A Simulation Study on Robustness of One Sample Inferential Statistics in Mixture Distribution
African Scientific Reports, 2022 Mixture distribution refers to the combination of more than one probability distribution. Meanwhile, non-normality of data set may be inevitable and the cause may be as a result of mixed distributions thereby renders parametric tests ineffective ...

A Tychonoff non‐normal space [PDF]
International Journal of Mathematics and Mathematical Sciences, 1993 Summary: A Tikhonov non-normal space is constructed which can be used for the construction of a regular space on which every weakly continuous (hence every \(\theta\)-continuous or \(\eta\)-continuous) map into a given space is constant. The construction is a modification of the space \(T_ 1(R)\) in [\textit{S. Iliadis} and the author, Can. J. Math. 38,

On The Normality Set of Linear Operators
مجلة بغداد للعلوم, 2020 In this paper, the Normality set will be investigated. Then, the study highlights some concepts properties and important results. In addition, it will prove that every operator with normality set has non trivial invariant subspace of .

Robustness of Identifying Item–Trait Relationships Under Non-Normality in MIRT Models
MathematicsIdentifying item–trait relationships is a core task in multidimensional item response theory (MIRT). Common empirical approaches include exploratory item factor analysis (EIFA) with rotations, the expectation maximization-based L1 regularization (EML1 ...

Clinical Insights Into Hypercalcemia of Malignancy in Childhood
Pediatric Blood &Cancer, EarlyView.ABSTRACT Hypercalcemia of malignancy (HCM) is a rare but life‐threatening metabolic emergency in children that occurs in less than 1% of pediatric cancer cases, with a reported incidence ranging from 0.4% to 1.0% across different studies. While it is observed in 10%–20% of adult malignancies, pediatric HCM remains relatively uncommon.

The estimation and decomposition of value-at-risk for non-normal portfolio returns
Journal of Business Economics and Management, 2013 Value-at-risk (VaR) is a widely used measure for evaluating the market risk of a trading portfolio. This article presents the g-and-h method for estimating the VaR of a portfolio with non-normal returns, and adds to the usefulness of VaR as a risk ...

Bootstrap for estimating the mean squared error of the spatial EBLUP [PDF]
, 2007 This work assumes that the small area quantities of interest follow a Fay-Herriot model with spatially correlated random area effects. Under this model, parametric and nonparametric bootstrap procedures are proposed for estimating the mean squared ...
