Analytic and numerical bootstrap for one-matrix model and “unsolvable” two-matrix model [PDF]

open access: yesJournal of High Energy Physics, 2022
We propose the relaxation bootstrap method for the numerical solution of multi-matrix models in the large N limit, developing and improving the recent proposal of H. Lin.

Studentized bootstrap model-averaged tail area intervals. [PDF]

open access: yesPLoS ONE, 2019
In many scientific studies, the underlying data-generating process is unknown and multiple statistical models are considered to describe it. For example, in a factorial experiment we might consider models involving just main effects, as well as those ...

Bootstrap Model-Based Constrained Optimization Tests of Indirect Effects [PDF]

open access: yesFrontiers in Psychology, 2020
In mediation analysis, conditions necessary for commonly recommended tests, including the confidence interval (CI)-based tests, to produce an accurate Type I error, do not generally hold for finite sample sizes and non-normally distributed model ...

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

open access: greenRussian 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.

Form factors of the sausage model obtained with bootstrap fusion from sine-Gordon theory [PDF]

open access: green, 1996
We continue the investigation of massive integrable models by means of the bootstrap fusion procedure, started in our previous work on O(3) nonlinear sigma model.

Bootstrap methods for inference in the Parks model [PDF]

open access: goldEconomics: Journal Articles, 2020
This paper shows how to bootstrap hypothesis tests in the context of the Parks’s (1967) Feasible Generalized Least Squares estimator. It then demonstrates that the bootstrap outperforms FGLS(Parks)’s top competitor.

Re-sampling in Linear Regression Model Using Jackknife and Bootstrap [PDF]

open access: goldالمجلة العراقية للعلوم الاحصائية, 2010
Statistical inference is based generally on some estimates that are functions of the data. Resampling methods offer strategies to estimate or approximate the sampling distribution of a statistic.

Prediction of Hourly Global Solar Radiation: Comparison of Neural Networks / Bootstrap Aggregating [PDF]

open access: yesKemija u Industriji, 2023
This research work explores the use of single neural networks and bootstrap aggregated neural networks for predicting hourly global solar radiation. A database of 3606 data points were from the Renewable Energies Development Center, radiometric station ...

The extraordinary boundary transition in the 3d O(N) model via conformal bootstrap [PDF]

open access: yes, 2021
This paper studies the critical behavior of the 3d classical $\mathrm{O}(N)$ model with a boundary. Recently, one of us established that upon treating $N$ as a continuous variable, there exists a critical value $N_c>2$ such that for $2 \leq N3$, under a ...
