Empirical likelihood inference in autoregressive models with time-varying variances

open access: yesStatistical Theory and Related Fields, 2022
This paper develops the empirical likelihood ( $ \mathrm {EL} $ ) inference procedure for parameters in autoregressive models with the error variances scaled by an unknown nonparametric time-varying function.

Forecasting the development of renewable energy sources in the Visegrad Group countries against the background of the European Union

open access: yesInternational Entrepreneurship Review, 2022
Objective: The aim of the article was to forecast the necessary pace of changes in the share of RES in the V4 countries resulting from the EU’s renewable energy sources directive compared to other European Union countries.

Nested AutoRegressive Models

open access: yesCoRR
AutoRegressive (AR) models have demonstrated competitive performance in image generation, achieving results comparable to those of diffusion models. However, their token-by-token image generation mechanism remains computationally intensive and existing solutions such as VAR often lead to limited sample diversity.

Profit rates in the developed capitalist economies: a time series investigation [PDF]

open access: yesPSL Quarterly Review, 2017
This paper examines whether there is empirical evidence to support the hypothesis of a secular decline in the economy-wide profit rates, as predicted by classical economic theories. We specifically consider profit rates in the OECD economies based on the

Wind and Sea Breeze Characteristics for the Offshore Wind Farms in the Central Coastal Area of Taiwan

open access: yesEnergies, 2022
Renewable energy is crucial for achieving net zero emissions. Taiwan has abundant wind resources and most major wind farms are offshore over the Taiwan Strait due to a lack of space on land.

First-order planar autoregressive model

open access: yesModern Stochastics: Theory and Applications
This paper establishes the conditions for the existence of a stationary solution to the first-order autoregressive equation on a plane as well as properties of the stationary solution.

Nonlinearity and Spatial Autocorrelation in Species Distribution Modeling: An Example Based on Weakfish (Cynoscion regalis) in the Mid-Atlantic Bight

open access: yesFishes, 2022
Nonlinearity and spatial autocorrelation are common features observed in marine fish datasets but are often ignored or not considered simultaneously in modeling. Both features are often present within ecological data obtained across extensive spatial and

Is an Apple an Orange? A Large Language Model Benchmark for Candidate Term Extraction and Subclass Decisions Against Upper Ontologies in Engineering and Materials Science

open access: yesAdvanced Engineering Materials, EarlyView.
Building machine‐readable vocabularies for materials science is slow, expert‐driven work. This study benchmarks 13 large language models on two of its first steps: finding candidate terms in engineering articles and deciding where they belong in a class hierarchy.

Heart Rate Modeling and Prediction Using Autoregressive Models and Deep Learning

open access: yesSensors, 2021
Physiological time series are affected by many factors, making them highly nonlinear and nonstationary. As a consequence, heart rate time series are often considered difficult to predict and handle.

The Grid Bootstrap and the Autoregressive Model [PDF]

open access: yesReview of Economics and Statistics, 1999
A “grid” bootstrap method is proposed for confidence-interval construction, which has improved performance over conventional bootstrap methods when the sampling distribution depends upon the parameter of interest. The basic idea is to calculate the bootstrap distribution over a grid of values of the parameter of interest and form the confidence ...
