Robust Estimators for the Correlation Measure to Resist Outliers in Data

open access: yesJournal of Mathematical and Fundamental Sciences, 2016
The objective of this research was to propose a composite correlation coefficient to estimate the rank correlation coefficient of two variables. A simulation study was conducted using 228 situations for a bivariate normal distribution to compare the ...

An improved estimator for non-Gaussianity in cosmic microwave background observations [PDF]

open access: yes, 2012
An improved estimator for the amplitude fnl of local-type non-Gaussianity from the cosmic microwave background (CMB) bispectrum is discussed. The standard estimator is constructed to be optimal in the zero-signal (i.e., Gaussian) limit.

The Triple Difference Estimator

open access: yesSocial Science Research Network, 2020
Triple difference has become a widely used estimator in empirical work. A close reading of articles in top economics journals reveals that the use of the estimator to a large extent rests on intuition.

Multiobjective tree-structured parzen estimator for computationally expensive optimization problems

open access: yesAnnual Conference on Genetic and Evolutionary Computation, 2020
Practitioners often encounter computationally expensive multiobjective optimization problems to be solved in a variety of real-world applications. On the purpose of challenging these problems, we propose a new surrogate-based multiobjective optimization ...

On some composite Kies families: distributional properties and saturation in Hausdorff sense

open access: yesModern Stochastics: Theory and Applications, 2023
The stochastic literature contains several extensions of the exponential distribution which increase its applicability and flexibility. In the present article, some properties of a new power modified exponential family with an original Kies correction ...

Estimation of a discrete monotone distribution [PDF]

open access: yes, 2009
We study and compare three estimators of a discrete monotone distribution: (a) the (raw) empirical estimator; (b) the "method of rearrangements" estimator; and (c) the maximum likelihood estimator.

Development and testing of a soot particle concentration estimator using Lagrangian post-processing

open access: yesEngineering Applications of Computational Fluid Mechanics, 2018
Soot emissions from combustion devices are known to have harmful effects on the environment and human health. As the transportation industry continues to expand, the development of techniques to reduce soot emissions remains a significant goal of ...
