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 ...

Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT We propose a multilevel econometric model with time‐varying spillover parameters that disentangle within‐country from between‐country growth spillovers. Parameter estimation is carried out by the method of maximum likelihood. The finite‐sample properties of the resulting estimates are validated through a Monte Carlo study.

Plant Biology, EarlyView.Early‐season hot drought in Scots pine limits growth and productivity but improves resilience to late‐season drought through reduced water use. Abstract Tree responses to drought are well studied, but the interacting effects of drought timing on growth, water use, and stress legacy are less understood.

Positive mixture effects in pine–oak forests during drought are context‐dependent
Plant Biology, EarlyView.Mixture effects in drought‐stressed pine‐oak forests are context‐dependent, with Gambel oak and ponderosa pine benefiting from their complementarity under semi‐arid conditions. Abstract The increasing severity and frequency of droughts will play a pivotal role in shaping future forest ecosystems worldwide.

Plant Biology, EarlyView.This study demonstrates the potential of the Sentinel‐1 Dual Polarimetric Radar Vegetation Index, combined with climate variables and the Standardized Precipitation–Evapotranspiration Index, to effectively detect and monitor drought‐induced stress in temperate broadleaf deciduous forests.

No legacy effects of severe drought on carbon and water fluxes in a Mediterranean oak forest
Plant Biology, EarlyView.A Mediterranean Quercus ilex forest was severely affected by a drought in 2017 but fully recovered in the following year, supported by favourable weather and growing conditions both before and after the event. Abstract Severe droughts affect vegetation through several processes, such as hydraulic failure, early leaf senescence, depletion of carbon ...
