Testing Cross-Sectional Correlation in Large Panel Data Models with Serial Correlation

open access: yesEconometrics, 2016
This paper considers the problem of testing cross-sectional correlation in large panel data models with serially-correlated errors. It finds that existing tests for cross-sectional correlation encounter size distortions with serial correlation in the ...

Heteroskedasticity, temporal and spatial correlation matter

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013
As economic time series or cross sectional data are typically affected by serial correlation and/or heteroskedasticity of unknown form, panel data typically contains some form of heteroskedasticity, serial correlation and/or spatial correlation ...

Can temporal covariation and autocorrelation in demographic rates affect population dynamics in a raptor species?

open access: yesEcology and Evolution, 2020
Theoretical studies suggest that temporal covariation among and temporal autocorrelation within demographic rates are important features of population dynamics.

Antithetic Power Transformation in Monte Carlo Simulation: Correcting Hidden Errors in the Response Variable

open access: yesMathematics, 2023
Monte Carlo simulation is performed with uniformly distributed U(0,1) pseudo-random numbers. Because the numbers are generated from a mathematical formula, they will contain some serial correlation, even if very small.

Stochastic aspects of motor behavior and their dependence on auditory feedback in experienced cellists

open access: yesFrontiers in Human Neuroscience, 2013
This study aimed to investigate movement accuracy of experienced cellists, the statistical properties of their note sequences during a reciprocal task, and the degree to which these movement characteristics depend on auditory feedback.

Canonical relations between intelligence and aggressiveness [PDF]

open access: yesPsihologija, 2002
Relation between results obtained from 25 tests for estimation of efficiency of perceptual, serial and parallel processor and 8 tests that estimate different modalities of aggressiveness, were analyzed under the biorthogonal model of canonical ...

Inter-regional correlation estimators for functional magnetic resonance imaging

open access: yesNeuroImage, 2023
Functional magnetic resonance imaging (fMRI) functional connectivity between brain regions is often computed using parcellations defined by functional or structural atlases. Typically, some kind of voxel averaging is performed to obtain a single temporal

tscount: An R Package for Analysis of Count Time Series Following Generalized Linear Models

open access: yesJournal of Statistical Software, 2017
The R package tscount provides likelihood-based estimation methods for analysis and modeling of count time series following generalized linear models. This is a flexible class of models which can describe serial correlation in a parsimonious way.

The contribution of pre-symptomatic infection to the transmission dynamics of COVID-2019 [version 1; peer review: 2 approved]

open access: yesWellcome Open Research, 2020
Background: Pre-symptomatic transmission can be a key determinant of the effectiveness of containment and mitigation strategies for infectious diseases, particularly if interventions rely on syndromic case finding. For COVID-19, infections in the absence

Tuning perception and decisions to temporal context

open access: yesiScience, 2023
Summary: Recent work suggests that serial dependence, where perceptual decisions are biased toward previous stimuli, arises from the prior that sensory input is temporally correlated.
