Multivariate Threshold Regression Models with Cure Rates: Identification and Estimation in the Presence of the Esscher Property

open access: yesStats, 2022
The first hitting time of a boundary or threshold by the sample path of a stochastic process is the central concept of threshold regression models for survival data analysis.

A regularized stochastic configuration network based on weighted mean of vectors for regression [PDF]

open access: yesPeerJ Computer Science, 2023
The stochastic configuration network (SCN) randomly configures the input weights and biases of hidden layers under a set of inequality constraints to guarantee its universal approximation property.

Stochastic Restricted Biased Estimators in Misspecified Regression Model with Incomplete Prior Information

open access: yesJournal of Probability and Statistics, 2018
The analysis of misspecification was extended to the recently introduced stochastic restricted biased estimators when multicollinearity exists among the explanatory variables. The Stochastic Restricted Ridge Estimator (SRRE), Stochastic Restricted Almost

Modelling daily water temperature from air temperature for the Missouri River [PDF]

open access: yesPeerJ, 2018
The bio-chemical and physical characteristics of a river are directly affected by water temperature, which thereby affects the overall health of aquatic ecosystems. It is a complex problem to accurately estimate water temperature.

Stochastic EM for Shuffled Linear Regression

open access: yesCoRR, 2018
We consider the problem of inference in a linear regression model in which the relative ordering of the input features and output labels is not known. Such datasets naturally arise from experiments in which the samples are shuffled or permuted during the protocol.

Stochastic regression and its application to hedging in finance [PDF]

open access: yes, 2009
In this paper we investigate how to employ stochastic regression to hedge risks in finance, where the risk of a security is measured by its quadratic variation process.

Multicollinearity applied stepwise stochastic imputation: a large dataset imputation through correlation-based regression

open access: yesJournal of Big Data, 2023
This paper presents a stochastic imputation approach for large datasets using a correlation selection methodology when preferred commercial packages struggle to iterate due to numerical problems. A variable range-based guard rail modification is proposed

Diverse Conditional Image Generation by Stochastic Regression with Latent Drop-Out Codes [PDF]

open access: yes, 2018
Recent advances in Deep Learning and probabilistic modeling have led to strong improvements in generative models for images. On the one hand, Generative Adversarial Networks (GANs) have contributed a highly effective adversarial learning procedure, but ...

ON THE USING OF THE SHANNON INFORMATION QUANTITY IN THE TASKS ASSOCIATED WITH LINEAR REGRESSION

open access: yesSt. Petersburg Polytechnical University Journal: Physics and Mathematics, 2019
The article discusses the use of the Shannon information quantity (SIQ) in the tasks associated with linear regression. It is shown that the SIQ contained in the response components with respect to stochastic parameters is expressed through the Fisher ...

A review on quantile regression for stochastic computer experiments

open access: yesReliability Engineering & System Safety, 2020
We report on an empirical study of the main strategies for quantile regression in the context of stochastic computer experiments. To ensure adequate diversity, six metamodels are presented, divided into three categories based on order statistics, functional approaches, and those of Bayesian inspiration.
