Cross-Market Herding: Do ‘Herds’ Herd with Each Other?
Journal of Behavioral Finance, 2022 Although herding constitutes one of the most widely researched behavioral trading patterns internationally, the possibility of cross-market herding has remained largely underexplored in the literature. Our study provides a detailed empirical investigation of this issue in the context of ten Asia-Pacific markets for the February 1995–March 2022 window ...

Statistics and Computing, 2023 AbstractHerding is a deterministic algorithm used to generate data points regarded as random samples satisfying input moment conditions. This algorithm is based on a high-dimensional dynamical system and rooted in the maximum entropy principle of statistical inference.

Trends in Cognitive Sciences, 2009 Herding is a form of convergent social behaviour that can be broadly defined as the alignment of the thoughts or behaviours of individuals in a group (herd) through local interaction and without centralized coordination.

Coronavirus herd immunity optimizer (CHIO)
Neural computing & applications (Print), 2020 In this paper, a new nature-inspired human-based optimization algorithm is proposed which is called coronavirus herd immunity optimizer (CHIO). The inspiration of CHIO is originated from the herd immunity concept as a way to tackle coronavirus pandemic ...
