Nonparametric Simultaneous Test Procedures

open access: yesRevista Colombiana de Estadística, 2015
In this research we propose several nonparametric simultaneous test procedures for location and scale parameters. We construct test statistics based on linear rank statistics choosing a suitable combining function.

On employment of methods of quantification of qualitative features in social science investigations [PDF]

open access: yesSociološki Pregled, 2005
The results from empirical sociological studies have to be objective and precise, yet the data processing methods applied should be a subject of verification. However, this is not the case in many studies, since the appropriate quantitative data analysis

Nonparametric test for spatial geometric anisotropy

open access: yesLietuvos Matematikos Rinkinys, 2010
Paper deals with a problem of testing isotropy against geometric anisotropy for Gaussian spatial data. The original simple test statistic based on directional empirical semivariograms is proposed.

A Comparison of Nonparametric Statistics and Bootstrap Methods for Testing Two Independent Populations with Unequal Variance

open access: yesInternational Journal of Analysis and Applications, 2023
The common parametric statistics used for testing two independent populations have often required the assumptions of normality and equal variances. Nonparametric tests have been used when assumptions of parametric tests cannot be achieved.

Tests for Independence in Nonparametric Regression [PDF]

open access: yes, 2006
Consider the nonparametric regression model Y = m(X)+e, where the function m is smooth, but unknown. We construct tests for the independence of e and X, based on n independent copies of (X; Y). The testing procedures are based on differences of neighboring Y's.

Robust-BD Estimation and Inference for General Partially Linear Models

open access: yesEntropy, 2017
The classical quadratic loss for the partially linear model (PLM) and the likelihood function for the generalized PLM are not resistant to outliers. This inspires us to propose a class of “robust-Bregman divergence (BD)” estimators of both the parametric

Use of Indices on Daily Timescales to Study Changes in Extreme Precipitation Across Nepal Over 40 Years (1976–2015)

open access: yesEarth and Space Science, 2023
This paper presents a comprehensive picture of extreme precipitation across Nepal from 1976 to 2015 based on high‐quality daily precipitation observations from 28 precipitation stations spatially distributed across the country.
