Nonlinear Autoregressive Model for Stability and Prediction

open access: yesJournal of Applied Mathematics
A proposed nonlinear autoregressive model was employed to predict daily new COVID-19 infections in Iraq. This model was applied to actual COVID-19 data from 3 months in 2022 and met the stability criteria set by the proposed nonlinear regression model ...

Nonlinear Autoregressive Latent Trajectory Models [PDF]

open access: yesSociological Methodology, 2018
Autoregressive latent trajectory (ALT) models combine features of latent growth curve models and autoregressive models into a single modeling framework. The development of ALT models has focused primarily on models with linear growth components, but some social processes follow nonlinear trajectories.

Autoregressive functions estimation in nonlinear bifurcating autoregressive models [PDF]

open access: yesStatistical Inference for Stochastic Processes, 2016
Bifurcating autoregressive processes, which can be seen as an adaptation of au-toregressive processes for a binary tree structure, have been extensively studied during the last decade in a parametric context. In this work we do not specify any a priori form for the two autoregressive functions and we use nonparametric techniques.

Prognostics for remaining useful life estimation in proton exchange membrane fuel cell by dynamic recurrent neural networks

open access: yesEnergy Reports, 2022
This paper proposes a nonlinear dynamic recurrent neural network (DRNN) prognostics method for predicting the performance degradation trend and estimating the remaining useful life (RUL) of a proton exchange membrane fuel cell (PEMFC). The conducted DRNN

Nonlinear autoregressive models with optimality properties [PDF]

open access: yesEconometric Reviews, 2019
We introduce a new class of nonlinear autoregressive models from their representation as linear autoregressive models with time-varying coefficients. The parameter updating scheme is subsequently based on the score of the predictive likelihood function at each point in time.

Nonlinear Modeling of Mortality Data and Its Implications for Longevity Bond Pricing

open access: yesRisks, 2023
Human mortality has been improving faster than expected over the past few decades. This unprecedented improvement has caused significant financial stress to pension plan sponsors and annuity providers. The widely recognized Lee–Carter model often assumes

Improving the accuracy of financial time series prediction using nonlinear exponential autoregressive models [PDF]

open access: yesMathematics and Modeling in Finance
In recent years, precise analysis and prediction of financial time series data have received significant attention. While advanced linear models provide suitable predictions for short and medium-term periods, market studies have indicated that stock ...

An Exponential Autoregressive Time Series Model for Complex Data

open access: yesMathematics, 2023
In this paper, an exponential autoregressive model for complex time series data is presented. As for estimating the parameters of this nonlinear model, a three-step procedure based on quantile methods is proposed. This quantile-based estimation technique
