Multiple Changepoint Detection for Non‐Gaussian Time Series
Journal of Time Series Analysis, EarlyView.ABSTRACT This article combines methods from existing techniques to identify multiple changepoints in non‐Gaussian autocorrelated time series. A transformation is used to convert a Gaussian series into a non‐Gaussian series, enabling penalized likelihood methods to handle non‐Gaussian scenarios.

Testing for Unspecified Periodicities in Binary Time Series
Journal of Time Series Analysis, EarlyView.ABSTRACT Given random variables Y1,…,Yn$$ {Y}_1,\dots, {Y}_n $$ with Yi∈{0,1}$$ {Y}_i\in \left\{0,1\right\} $$ we test the hypothesis whether the underlying success probabilities pi$$ {p}_i $$ are constant or whether they are periodic with an unspecified period length of r≥2$$ r\ge 2 $$.

Detecting Relevant Deviations From the White Noise Assumption for Non‐Stationary Time Series
Journal of Time Series Analysis, EarlyView.ABSTRACT We consider the problem of detecting deviations from a white noise assumption in time series. Our approach differs from the numerous methods proposed for this purpose with respect to two aspects. First, we allow for non‐stationary time series. Second, we address the problem that a white noise test is usually not performed because one believes ...

Evolutionary correlates and consequences of sociality in feliform carnivorans
Journal of Zoology, EarlyView.We take a phylogenetic comparative approach to investigate the evolutionary correlates of sociality in feliform (cat‐like) carnivores. We find that sociality evolved eight times in this group of mammals, and that it is associated with ecologies that facilitate group cohesion (e.g. diurnality and open habitats) and also that should reduce competition (e.
