Big Bayes is the computationally intensive co-application of big data and large, expressive Bayesian models for the analysis of complex phenomena in scientific inference and statistical learning. Standing as an example, Bayesian multidimensional scaling (MDS) can help scientists learn viral trajectories through space-time, but its computational bur...
We report the observation of a compact binary coalescence involving a 22.2-24.3 M⊙ black hole and a compact object with a mass of 2.50-2.67 M⊙ (all measurements quoted at the 90% credible level). The gravitational-wave signal, GW190814, was observed during LIGO's and Virgo's third observing run on 2019 August 14 at 21:10:39 UTC and has a signal-to-...
В статье исследуются особенности влияния информационно-технического прогресса на выбор молодежью своей жизненной позиции применительно к России. Выявляются основные тенденции этого процесса в советский и постсоветский периоды. Отмечается, что в настоящее время отсутствуют четко определенные ориентиры для поведенческих установок молодых людей, и в т...

We investigate an optimal growth portfolio problem with contingent convertible bonds (CoCos). As the conversion risk in CoCos is closely associated with the issuer's capital structure and the stock price at conversion, we model both equity and credit risk to frame this optimisation problem. This study aims to answer two questions that (i) how inves...

© 2018, Springer Nature Limited. National probability election surveys are more and more abandoned. Decreasing response rates and the escalating costs of face-to-face and telephone interviews have strengthened election scholars’ reliance on nonprobability internet samples to conduct election surveys online. In a number of countries, experiments wit...
Many financial portfolios are not mean-variance-skewness-kurtosis efficient. We recommend tilting these portfolios in a direction that increases their estimated mean and third central moment and decreases their variance and fourth central moment. The advantages of tilting come at the cost of deviation from the initial optimality criterion. In this ...
