Resampling Plans and the Estimation of Prediction Error

open access: yesStats, 2021
This article was prepared for the Special Issue on Resampling methods for statistical inference of the 2020s. Modern algorithms such as random forests and deep learning are automatic machines for producing prediction rules from training data.

A new distribution-free approach to constructing the confidence region for multiple parameters. [PDF]

open access: yesPLoS ONE, 2013
Construction of confidence intervals or regions is an important part of statistical inference. The usual approach to constructing a confidence interval for a single parameter or confidence region for two or more parameters requires that the distribution ...

An integrated approach for the analysis of biological pathways using mixed models. [PDF]

open access: yesPLoS Genetics, 2008
Gene class, ontology, or pathway testing analysis has become increasingly popular in microarray data analysis. Such approaches allow the integration of gene annotation databases, such as Gene Ontology and KEGG Pathway, to formally test for subtle but ...

Effects of dating errors on nonparametric trend analyses of speleothem time series [PDF]

open access: yesClimate of the Past, 2012
A fundamental problem in paleoclimatology is to take fully into account the various error sources when examining proxy records with quantitative methods of statistical time series analysis.

dbEmpLikeGOF: An R Package for Nonparametric Likelihood Ratio Tests for Goodness-of-Fit and Two-Sample Comparisons Based on Sample Entropy

open access: yesJournal of Statistical Software, 2013
We introduce and examine dbEmpLikeGOF, an R package for performing goodness-of-fit tests based on sample entropy. This package also performs the two sample distribution comparison test.

The efficiency of different search strategies in estimating parsimony jackknife, bootstrap, and Bremer support

open access: yesBMC Evolutionary Biology, 2005
Background For parsimony analyses, the most common way to estimate confidence is by resampling plans (nonparametric bootstrap, jackknife), and Bremer support (Decay indices).

Mapping topographic structure in white matter pathways with level set trees.

open access: yesPLoS ONE, 2014
Fiber tractography on diffusion imaging data offers rich potential for describing white matter pathways in the human brain, but characterizing the spatial organization in these large and complex data sets remains a challenge. We show that level set trees-

Permutation-Based Analysis of Clinical Variables in Necrotizing Fasciitis Using NPC and Bootstrap

open access: yesMathematics
Necrotizing fasciitis (NF) is a rare but aggressive soft tissue infection with high rates of mortality and amputation, making early identification of key prognostic biomarkers essential for clinical management. However, the rarity and heterogeneity of NF

Nonparametric Bootstrap Likelihood Estimation to Investigate the Chance Set-Up on Clustering Results

open access: yesIEEE Open Journal of the Computer Society
Clustering algorithms are widely used in the knowledge discovery domain, but concerns and questions about the validity of the results must be considered.
