Pruning and Nonparametric Multiple Change Point Detection

open access: yes, 2017
Change point analysis is a statistical tool to identify homogeneity within time series data. We propose a pruning approach for approximate nonparametric estimation of multiple change points.

Nonparametric Strategy Test

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference
We present a nonparametric statistical test for determining whether an agent is following a given mixed strategy in a repeated strategic-form game given samples of the agent's play.

Prioritizing spatial accuracy in high-resolution fMRI data using multivariate feature weight mapping

open access: yesFrontiers in Neuroscience, 2014
Although ultra-high-field fMRI at field strengths of 7T or above provides substantial gains in BOLD contrast-to-noise ratio, when very high-resolution fMRI is required such gains are inevitably reduced.

A nonparametric Bayesian method of translating machine learning scores to probabilities in clinical decision support

open access: yesBMC Bioinformatics, 2017
Background Probabilistic assessments of clinical care are essential for quality care. Yet, machine learning, which supports this care process has been limited to categorical results.

ESTIMATION OF A BI-RESPONSE TRUNCATED SPLINE NONPARAMETRIC REGRESSION MODEL ON LIFE EXPECTANCY AND PREVALENCE OF UNDERWEIGHT CHILDREN IN INDONESIA

open access: yesBarekeng, 2023
Researchers use the nonparametric regression method because it provides excellent flexibility in the modeling process. Nonparametric regression procedures can be used if the relationship pattern between the predictor and response variables is unknown ...

Rates of contraction for posterior distributions in $\bolds{L^r}$-metrics, $\bolds{1\le r\le\infty}$

open access: yes, 2011
The frequentist behavior of nonparametric Bayes estimates, more specifically, rates of contraction of the posterior distributions to shrinking $L^r$-norm neighborhoods, $1\le r\le\infty$, of the unknown parameter, are studied. A theorem for nonparametric

Fundamentals of Nonparametric Statistical Tests for Dental Clinical Research

open access: yesDentistry Journal
This article provides the foundation for employing nonparametric testing in dental clinical research. To make wise judgments in their research, investigators should learn more about the main nonparametric tests and their particular uses.

Bias of the Entropy Estimator for Symmetric Bernoulli Measures and the Weak Metric

open access: yesМоделирование и анализ информационных систем, 2015
We consider symmetric Bernoulli measures and new weak metrics and obtain a closed-form expression of the entropy estimator bias.

Identifying Factors Influencing the Corrosion Rate of Steel Using Nonparametric Statistics

open access: yesInternational Journal of Electrochemical Science, 2012
Statistical techniques have made it possible to describe the behavior of certain phenomena. Nonetheless, given the difficulty in obtaining adequate data, it is common not to have random and homogeneous samples in order to conduct parametric statistical ...

Functional single index models for longitudinal data

open access: yes, 2011
A new single-index model that reflects the time-dynamic effects of the single index is proposed for longitudinal and functional response data, possibly measured with errors, for both longitudinal and time-invariant covariates.
