Variance Matrix Priors for Dirichlet Process Mixture Models With Gaussian Kernels

International Statistical Review, EarlyView.
Summary Bayesian mixture modelling is widely used for density estimation and clustering. The Dirichlet process mixture model (DPMM) is the most popular Bayesian non‐parametric mixture modelling approach. In this manuscript, we study the choice of prior for the variance or precision matrix when Gaussian kernels are adopted.

No support for solar radiation as a major evolutionary driver of malar stripes in falcons

Journal of Avian Biology, EarlyView.
The malar stripes of falcons (Falco spp.) are often hypothesised to function by reducing the amount of solar glare reflected into the falcon's eyes while hunting, thereby aiding foraging efficiency in bright conditions. This ‘solar glare hypothesis' is supported by intraspecific trends in peregrine falcons Falco peregrinus, in which populations ...

Theories of market selection

Journal of Economic Surveys, EarlyView.
Abstract We provide a survey of the main mechanisms of market selection used in economics. We categorize existing theories into three broad classes—evolutionary selection, reduced form selection, and rational equilibrium—based on their adopted selection mechanisms.

Domestic Misfits, Social Physics and the Problem of International Statistical Standardization

Sociology Lens, EarlyView.
ABSTRACT During the 19th century, driven by the ideas of Adolphe Quetelet, population statistics were actively being developed and debated by many nascent nation‐states. The International Statistical Institute (ISI) was one of the premier statistical organizations of the 19th and 20th centuries that possessed a very international and prestigious ...

A Stochastic Tree for Bubble Asset Modelling and Pricing

Journal of Time Series Analysis, EarlyView.
ABSTRACT We introduce a new stochastic tree representation of a strictly stationary submartingale process for modelling, forecasting, and pricing speculative bubbles on commodity and cryptocurrency markets. The model is compared to other trees proposed in the literature on bubble asset modelling and stochastic volatility approximation. We show that the
