An extension of the statistical bootstrap model to include strangeness. Implications on particle ratios [PDF]

open access: yes, 1997
The Statistical Bootstrap Model (SBM) is extended to describe hadronic systems which carry the quantum number of strangeness. The study is conducted in the three-dimensional space of temperature, up-down and strange chemical potentials, wherein the ...

Model Error (or Ambiguity) and Its Estimation, with Particular Application to Loss Reserving

open access: yesRisks, 2023
This paper is concerned with the estimation of forecast error, particularly in relation to insurance loss reserving. Forecast error is generally regarded as consisting of three components, namely parameter, process and model errors.

Bootstrapping heteroskedastic regression models: wild bootstrap vs. pairs bootstrap [PDF]

open access: yesComputational Statistics & Data Analysis, 2005
In regression models, appropriate bootstrap methods for inference robust to heteroskedasticity of unknown form are the wild bootstrap and the pairs bootstrap. The finite sample performance of a heteroskedastic-robust test is investigated with Monte Carlo experiments.

A BOOTSTRAP APPROACH TO TESTING FOR SYMMETRY IN THE GRANGER AND LEE ASYMMETRIC ERROR CORRECTION MODEL [PDF]

open access: yesRussian Journal of Agricultural and Socio-Economic Sciences, 2012
The power of the Granger and Lee (1989) model of asymmetry is examined via bootstrap simulation. The results of the bootstrap simulation indicate that the Granger and Lee model has low power in rejecting the null hypothesis of symmetric adjustments.

Forest Fire Susceptibility Prediction Based on Machine Learning Models with Resampling Algorithms on Remote Sensing Data

open access: yesRemote Sensing, 2020
This study predicts forest fire susceptibility in Chaloos Rood watershed in Iran using three machine learning (ML) models—multivariate adaptive regression splines (MARS), support vector machine (SVM), and boosted regression tree (BRT). The study utilizes

Bootstrap Inference for Hawkes and General Point Processes [PDF]

open access: yesarXiv, 2021
Inference and testing in general point process models such as the Hawkes model is predominantly based on asymptotic approximations for likelihood-based estimators and tests. As an alternative, and to improve finite sample performance, this paper considers bootstrap-based inference for interval estimation and testing.

Efficient bootstrap estimates for tail statistics [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2017
Bootstrap resamples can be used to investigate the tail of empirical distributions as well as return value estimates from the extremal behaviour of the sample.

The Wild Bootstrap for Multilevel Models

open access: yesCommunications in Statistics - Theory and Methods, 2015
In this paper we study the performance of the most popular bootstrap schemes for multilevel data. Also, we propose a modified version of the wild bootstrap procedure for hierarchical data structures. The wild bootstrap does not require homoscedasticity or assumptions on the distribution of the error processes.

The Local Projection Residual Bootstrap for AR(1) Models [PDF]

open access: yesarXiv, 2023
This paper proposes a local projection residual bootstrap method to construct confidence intervals for impulse response coefficients of AR(1) models. Our bootstrap method is based on the local projection (LP) approach and involves a residual bootstrap procedure applied to AR(1) models.

Bootstrapping Exchangeable Random Graphs [PDF]

open access: yesElectronic Journal of Statistics, vol. 16 (2022), pp. 1058--1095, 2017
We introduce two new bootstraps for exchangeable random graphs. One, the "empirical graphon bootstrap", is based purely on resampling, while the other, the "histogram bootstrap", is a model-based "sieve" bootstrap. We show that both of them accurately approximate the sampling distributions of motif densities, i.e., of the normalized counts of the ...
