A prelude to statistics in Wasserstein metric spaces

Chon Van Le; Uyen Hoang Pham - In: Asian journal of economics and banking : AJEB 8 (2024) 1, pp. 54-66

, where the metric on probability measures is taken as a Wasserstein metric arising from optimal transport theory. Design …/methodology/approach - The authors spell out the basis and rationale for using Wasserstein metrics on the data space of (random) probability … measures. Findings - In elaborating the new statistical analysis of non-Euclidean data sets, the paper illustrates the …

Time-series Modelling, Stationarity and Bayesian Nonparametric Methods

Martínez-Ovando, Juan Carlos; Walker, Stephen G. - Banco de México - 2011

In this paper we introduce two general non-parametric first-order stationary time-series models for which marginal (invariant) and transition distributions are expressed as infinite-dimensional mixtures. That feature makes them the first Bayesian stationary fully non-parametric models developed...

A note on the fundamental theorem of asset pricing under model uncertainty

Bayraktar, Erhan; Zhang, Yuchong; Zhou, Zhou - In: Risks 2 (2014) 4, pp. 425-433

We show that the recent results on the Fundamental Theorem of Asset Pricing and the super-hedging theorem in the context of model uncertainty can be extended to the case in which the options available for static hedging (hedging options) are quoted with bid-ask spreads. In this set-up, we need...

Biased Bayesian Learning with an Application to the Risk-Free Rate Puzzle

Ludwig, Alexander; Zimper, Alexander - Economic Research Southern Africa (ERSA) - 2013

Based on the axiomatic framework of Choquet decision theory, we develop a closed-form model of Bayesian learning with ambiguous beliefs about the mean of a normal distribution. In contrast to rational models of Bayesian learning the resulting Choquet Bayesian estimator results in a long-run bias...
