Extremely Fast Maximum Likelihood Estimation of High‐Order Autoregressive Models
Journal of Time Series Analysis, EarlyView.ABSTRACT We consider the problem of exact maximum likelihood estimation of potentially high‐order (p>50$$ p>50 $$) autoregressive models. We propose an extremely fast coordinate‐wise algorithm for fitting autoregressive models. This fast algorithm exploits several properties of the negative log‐likelihood when parameterised in terms of partial ...

Restoration Ecology, EarlyView.Abstract Introduction Habitat restoration is applied to promote ecological recovery in degraded freshwater systems. However, it remains unclear whether stream restoration measures enhance Water Framework Directive (WFD) ecological status and biodiversity.

Team Cognition Research Is Transforming Cognitive Science
Topics in Cognitive Science, EarlyView.Abstract About 30 years ago, the Dynamical Hypothesis instigated a variety of insights and transformations in cognitive science. One of them was the simple observation that, quite unlike trial‐based tasks in a laboratory, natural ecologically valid behaviors almost never have context‐free starting points.

Myths and methodologies: Exposure and measurements under normobaric hypoxia
Experimental Physiology, EarlyView.Abstract Usually, settings of normobaric hypoxia underestimate the environmental hypoxia they are supposed to reproduce. The likely steady state of water vapour pressure within the human airways keeps the partial pressure of inspired oxygen very close to the assumed value, but this does not apply to the calculation of environmental hypoxia or ...
