Methods in Ecology and Evolution, EarlyView.Abstract Animal ecologists frequently quantify variance in hierarchically structured traits in wild populations. Importantly, phenotypic plasticity within the period of measurement can modify the trait of interest in response to various unmeasured, temporally or spatially changeable, environmental conditions.

Estimating the Parameters of Degradation Models when Error Terms are Autocorrelated
Austrian Journal of Statistics, 2016 The need of autocorrelation models for degradation data comes from the facts that the degradation measurements are often correlated, since such measurements are taken over time.

Autocorrelated errors explain the apparent relationship between disapproval of the US Congress and prosocial language [PDF]
, 2015 Recently, it has been claimed by Frimer et al. (2015) that there is a linear relationship between the level of prosocial language and the level of public disapproval of US Congress.

ASIdE: Using Autocorrelation-Based Size Estimation for Scheduling Bursty Workloads. [PDF]
, 2012 Temporal dependence in workloads creates peak congestion that can make service unavailable and reduce system performance. To improve system performability under conditions of temporal dependence, a server should quickly process bursts of requests that ...

Animal Conservation, EarlyView.The rapid expansion of wind energy across the Mediterranean region calls for more advanced tools to assess and mitigate its impacts on biodiversity. In this study, we present an innovative approach combining 13‐year satellite imagery analysis and ecological modelling, to assess the spatiotemporal overlap between wind energy development and habitat ...

Quality control of DEMs using check surfaces
Annals of GISThis paper proposes the use of check surfaces or ‘patches’ for the assessment of Digital Elevation Model (DEM) elevations and derived variables (e.g. slope and aspect).

Subsampling Inference for the Autocorrelations of GARCH Processes*
Journal of Financial Econometrics, 2017 AbstractWe provide self-normalization for the sample autocorrelations of power GARCH(p, q) processes whose higher moments might be infinite. To validate the studentization, whose goal is to match the growth rate dependent on the index of regular variation of the process, we substantially extend existing weak-convergence results.

Animal Conservation, EarlyView.The gopher tortoise (Gopherus polyphemus), a keystone species and ecosystem engineer, has declined by ~80% over the past century due to primarily habitat loss. In a 28‐year resurvey of federally protected Mobile County and state‐protected Baldwin County, we found tortoise populations persisted at ~59% and ~31% of sites, respectively, with significant ...

Monitoring Processes with Changing Variances [PDF]
Statistical process control (SPC) has evolved beyond its classical applications in manufacturing to monitoring economic and social phenomena. This extension requires consideration of autocorrelated and possibly non-stationary time series.
