Sequential Outlier Detection in Nonstationary Time Series

open access: yesJournal of Time Series Analysis, EarlyView.
ABSTRACT A novel method for sequential outlier detection in nonstationary time series is proposed. The method tests the null hypothesis of “no outlier” at each time point, addressing the multiple testing problem by bounding the error probability of successive tests, using extreme‐value theory. The asymptotic properties of the test statistic are studied

Analyzing Non‐Random Selectivity in Online Job Advertisements Using Eurostat Benchmark Data and Generalized Sample Selection Models: An Application to EU Regional Labor Markets

open access: yesLABOUR, EarlyView.
ABSTRACT The present paper provides an overall framework to afford the problem of non‐representativeness and non‐random selectivity arising from online job ads data, using Generalized sample selection models and Eurostat benchmark data. We jointly model the outcome intensity (number of online job ads in observed profiles, whose levels are defined by ...

Alleles From Crop Wild Relatives Accumulated by Long‐Term Adaptation to Low‐Input Environments Contribute to Yield Advantages in Wheat (Triticum aestivum)

open access: yesPlant Breeding, EarlyView.
ABSTRACT Increasingly variable climate conditions are affecting crop production, leading to greater yield fluctuations, which in turn are impacting global food security. Introducing alleles from regions where the expected stress conditions occur, so‐called exotic alleles, could serve as a means to mitigate these effects. We examined the value of exotic

Rearing duration influences survival rate in the Post‐Larval Capture, Culture and Release of a coral reef fish

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Juvenile coral reef fish face an initial predation‐induced mortality bottleneck with mortality exceeding 60% within 48 hours of settlement. This intense predation, exacerbated by anthropogenic stressors, limits recruitment and contributes to global declines of reef fish populations. Post‐Larval Capture, Culture, and Release (PCCR),
