ADISTA22: Advances in Directional Statistics. Santiago de Compostela15-17th June, 2022. Programme and Book of Abstracts

This book of proceedings collects the abstracts of the talks and posters presented at the third International Workshop on Advances in Directional Statistics (ADISTA22). It was a great pleasure to be able to meet during these trying times of the continuing COVID-19 pandemic, and we are grateful to all those who have collaborated in the ADISTA22 organization. In order to allay potential fears of contracting COVID on long journeys to Santiago de Compostela, the workshop has been organized to have a hybrid format with talks and posters presented both by those participating in person in Santiago and by others participating online from their home countries. We consider this to be the optimal format for the workshop in the current circumstances. Despite the challenges posed by the pandemic, we were delighted to be able to welcome all 57 participants who took up our invitation to participate in the workshop: 33 in person and 24 online, from no less than 18 countries (Australia, Belgium, Canada, France, Germany, Italy, Japan, Luxembourg, Mexico, Norway, Portugal, South Africa, South Korea, Spain, Taiwan, Turkey, UK, USA). One of the central themes of the postponed ADISTA20 workshop was to be a celebration of Kanti Mardia’s 85th Birthday. However, its postponement meant that we were unable to mark that event collectively. Instead, ADISTA22 provided a venue to celebrate another landmark event in the development of the field: namely, the publication 50 years ago, in 1972, of Kanti’s seminal monograph Statistics of Directional Data. Since its publication, the field of Directional Statistics has had periods in which its development has been more vigorous than in others, with interesting new applications often stimulating renewed interest. We sincerely hope that the workshop has provided a vehicle for stimulating dialogue and collaboration, leading to important future developments in the field. We would like to thank most sincerely the University of Santiago de Compostela (USC) for hosting the workshop and the following institutions for their financial and institutional support of the workshop: The Department of Statistics, Mathematical Analysis and Optimization (USC); The Faculty of Mathematics (USC); The Galician Centre for Mathematical Research and Technology (CITMAga); The Galician Society for the Promotion of Statistics and Operations Research (SGAPEIO); The Galician Statistics Institute (IGE); The Spanish Society of Statistics and Operations Research (SEIO); The Italian Society of Statistics (SIS); The Luxembourg Statistical Society (LSS). Finally, we very much hope that this book of abstracts will be enjoyable and stimulating for all of those participating in the ADISTA22, and for all the scientific community interested in Directional Statistics
