Bandwidth Selection for Prediction in Regression

open access: yesProceedings, 2019
There exist many different methods to choose the bandwidth in kernel regression. If, however, the target is regression based prediction for samples or populations with potentially different distributions, then the existing methods can easily be ...

Identificaton and Diversity of Endophytic Fungi Associated with The Seagrasses of Cebu, Central Philippines

open access: yesBiotropia: The Southeast Asian Journal of Tropical Biology, 2023
Endophytic fungi were poorly documented in the marine environment, especially in seagrasses regardless of their importance as sources of novel metabolites. In the Philippines, studies are dearth despite having large areas of seagrass meadows. Thus, this

On a linear method in bootstrap confidence intervals

open access: yesStatistica, 2007
A linear method for the construction of asymptotic bootstrap confidence intervals is proposed. We approximate asymptotically pivotal and non-pivotal quantities, which are smooth functions of means of n independent and identically distributed random ...

On confidence intervals centred on bootstrap smoothed estimators [PDF]

open access: yesStat, 2019
Bootstrap smoothed (bagged) estimators have been proposed as an improvement on estimators found after preliminary data‐based model selection. Efron derived a widely applicable formula for a delta method approximation to the standard deviation of the bootstrap smoothed estimator. He also considered a confidence interval centred on the bootstrap smoothed

Convergent momentum-space OPE and bootstrap equations in conformal field theory

open access: yesJournal of High Energy Physics, 2020
General principles of quantum field theory imply that there exists an operator product expansion (OPE) for Wightman functions in Minkowski momentum space that converges for arbitrary kinematics.

The missing censoring indicator model and the smoothed bootstrap [PDF]

open access: yesComputational Statistics & Data Analysis, 2008
For right censored data with missing censoring indicators, sub-density function kernel estimators play a significant role for estimating a survival function. Data-driven bandwidths for computing these kernel estimators are proposed. The bandwidths are obtained as minimizers of certain estimates of the mean integrated squared error (MISE).

60-V Non-Inverting Four-Mode Buck–Boost Converter With Bootstrap Sharing for Non-Switching Power Transistors

open access: yesIEEE Access, 2020
This paper presents a non-inverting buck-boost converter for high-voltage automotive applications. The converter includes a newly proposed controller chip and four off-chip NMOS power transistors with two bootstrap capacitors.

Computationally Efficient Bootstrap Expressions for Bandwidth Selection in Nonparametric Curve Estimation

open access: yesProceedings, 2018
Bootstrap methods are used for bandwidth selection in: (1) nonparametric kernel density estimation with dependent data (smoothed stationary bootstrap and smoothed moving blocks bootstrap), and (2) nonparametric kernel hazard rate estimation (smoothed ...

The Smoothed Bootstrap Fine-Tuning [PDF]

open access: yesSystem Safety: Human - Technical Facility - Environment, 2019
Abstract The bootstrap method is a well-known method to gather a full probability distribution from the dataset of a small sample. The simple bootstrap i.e. resampling from the raw dataset often leads to a significant irregularities in a shape of resulting empirical distribution due to the discontinuity of a support.
