A Conway–Maxwell–Poisson-Binomial AR(1) Model for Bounded Time Series Data [PDF]

open access: yesEntropy, 2023
Binomial autoregressive models are frequently used for modeling bounded time series counts. However, they are not well developed for more complex bounded time series counts of the occurrence of n exchangeable and dependent units, which are becoming ...

Testing AR(1) model

open access: yesLietuvos Matematikos Rinkinys, 2021
In this paper we investigate a simple AR(1) model by testing a presence of changed segment in a data. We suggest test statistics based on a behavior of partial sums of residuals.

Implied Volatility Prediction Based on Different Term Structures: An Empirical Study of the SSE 50 ETF Options Market from High-Frequency Data [PDF]

open access: yesE3S Web of Conferences, 2021
This article focuses on the implied volatility forecast of the SSE 50 ETF options market from June 1, 2017, to August 30, 2019, and constructs AR (1) model and ARMA-GARCH model based on liquidity characteristics to compare and analyze the prediction ...

Predictive study of tuberculosis incidence by time series method and Elman neural network in Kashgar, China

open access: yesBMJ Open, 2021
Objectives Kashgar, located in Xinjiang, China has a high incidence of tuberculosis (TB) making prevention and control extremely difficult. In addition, there have been very few prediction studies on TB incidence here. We; therefore, considered it a high

HIF-1-Dependent Induction of β3 Adrenoceptor: Evidence from the Mouse Retina

open access: yesCells, 2022
A major player in the homeostatic response to hypoxia is the hypoxia-inducible factor (HIF)-1 that transactivates a number of genes involved in neovessel proliferation in response to low oxygen tension.

Controlled Parameter Estimation for The AR(1) Model with Stationary Gaussian Noise

open access: yesFractal and Fractional, 2022
This paper deals with the maximum likelihood estimator for the parameter of first-order autoregressive models driven by the stationary Gaussian noises (Colored noise) together with an input. First, we will find the optimal input that maximizes the Fisher

Stochastic simulation in reservoir sedimentation estimation: application in a PCH

open access: yesAnais da Academia Brasileira de Ciências, 2022
In reservoir projects it is important to estimate when the accumulated sediments will start to interfere with their functions. However, predicting silting is difficult because the processes involved have some uncertainties.

Modeling Best Practice Life Expectancy Using Gumbel Autoregressive Models

open access: yesRisks, 2021
Best practice life expectancy has recently been modeled using extreme value theory. In this paper we present the Gumbel autoregressive model of order one—Gumbel AR(1)—as an option for modeling best practice life expectancy. This class of model represents

Estimation of heritability using half-sib model under correlated errors

open access: yesIndian Journal of Animal Sciences, 2022
In general, statistical models for estimation of heritability follow certain assumptions, i.e. random components including the error follow a normal distribution and are identically independently distributed.
