Not all Temperature Shocks are Alike: Disentangling Heat and High Temperature Shocks and Their Effects on Inflation in Australia

open access: yesEconomic Record, EarlyView.
We study the effects of heat and high temperature shocks on inflation in Australia using monthly, state‐level temperature anomaly data via two stages. In the first stage, we decompose temperature anomalies into orthogonal components using a structural vector autoregression with long‐run restrictions.

Ecological examples of nonstationarity, nonlinearity and statistical interactions in dynamic structural equation models

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Ecologists are adapting structural causal modelling for spatial, phylogenetic and time‐series analysis. However, ecological extensions of path analysis and structural equation models (SEM) typically assume that interactions among variables are stationary, linear and additive, while ecological and evolutionary dynamics are often nonstationary ...

A Proposed Autocorrelated Process Monitoring System

open access: yes, 2013
Klasické metody statistického řízení procesů (SPC), jako jsou Shewhartovy regulační diagramy a CUSUM regulační diagramy, předpokládají, že získaná procesní data jsou nezávislá.

Cluster analysis for autocorrelated and cyclic chemical process data

open access: yes, 2007
A clustering algorithm based on principal components analysis (PCA) is proposed for clustering autocorrelated and cyclic data sets typical of continuous chemical processes.

Burrow Persistence and Spatial Distribution of Federally and State‐Protected Gopher Tortoise (Gopherus polyphemus) Populations in Southwest Alabama

open access: yesAnimal 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 ...

Beyond Sporting Talent: Other Determinants of Football Clubs’ Wage Bills

open access: yesBulletin of Economic Research, EarlyView.
ABSTRACT This article delves into the understanding of how football clubs determine wage bills to compensate talent. Using data from first‐division teams in elite European leagues, we estimate wage models based on indicators of sporting performance, “Elo ratings” as a proxy for clubs’ historical achievements and brand strength, and “media visibility ...

Quality control of DEMs using check surfaces

open access: yesAnnals of GIS
This 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).

Estimating the Parameters of Degradation Models when Error Terms are Autocorrelated

open access: yesAustrian 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.

Monitoring of the BTA Deep Hole Drilling Process Using Residual Control Charts [PDF]

open access: yes
Deep hole drilling methods are used for producing holes with a high lengthto- diameter ratio, good surface finish and straightness. The process is subject to dynamic disturbances usually classified as either chatter vibration or spiralling. In this work,
