A Generalized Portmanteau Test for Independence of Two Infinite Order Vector Autoregressive Series [PDF]
In many situations, we want to verify the existence of a relationship between multivariate time series. Here, we propose a semiparametric approach for testing the independence between two infinite order vector autoregressive (VAR()) series which is an ...

On The Modified Divergence Information Criterion
Ibn Al-Haitham Journal for Pure and Applied Sciences, 2016 In this work (paper), we investigate about the robustness of the modified divergence Information Criterion (MDIC), which proposed by Mantalos, Mattheou and Karagrigoriou (2008), to determine the probability of the Criterion picking up the true lag for ...

Robust Regression Analysis of Longitudinal Data under Censoring
Austrian Journal of Statistics, 2017 We consider regression analysis of longitudinal data when the temporal correlation is modeled by an autoregressive process. Robust R estimators of regression and autoregressive parameters are obtained.

Advanced Intelligent Systems, EarlyView.A physics‐guided deep learning framework, ParamNet, is introduced for the intelligent self‐inversion of vacuum optical tweezers. By fuzing dual‐branch time–frequency features with physical dynamical constraints, it achieves high‐accuracy calibration of trap parameters from short‐window, low‐frequency trajectories, outperforming traditional methods ...

An unconditional maximum likelihood test for a unit root [PDF]
, 1993 We investigate a test for unit roots in autoregressive time series based on maximization of the unconditional likelihood. This is the likelihood function appropriate for stationary time series.

American Journal of Community Psychology, EarlyView.Abstract The current study seeks to explore the reciprocal associations between mentor–mentee relationship strength and relationships with parents and peers across 2 years of mentoring. It is a secondary analysis of data collected by a national mentoring organization from youth (N = 1368; M age = 11.5 years; 59% female; White [n = 629], 30% Black [n ...

Change in autoregressive processes
Stochastic Processes and their Applications, 1993 The paper studies the detection of a possible change in a stationary autoregressive process of order \(r\). The test statistics are based on weighted supremum and \(L_ p\)-functionals of the residual sums. Some limit theorems are proven under necessary and sufficient conditions.
