The European Regional Section of the International Association for Statistical Computing (IASC-ERS), the International Association for Statistical Computing (IASC), and the International Statistical Institute (ISI) held a successful Webinar on functional data analysis on April 29-30, 2021. The IASC-ERS Webinar Course “An Introduction to Functional Data Analysis for Density Functions in Bayes Spaces” was team-taught by Alessandra Menafoglio (Politecnico di Milano), Karel Hron (Palacký University) and Jitka Machalová (Palacký University).
175 students pre-registered for the course on the GoToWebinar platform. 132 (75%) students attended the course on the first day and 94 (54%) on the second day. Participants came from 44 different countries: Argentina, Australia, Austria, Belgium, Brazil, Canada, Chile, China, Côte d’Ivoire, Croatia, Czech Republic, Denmark, Finland, France, Germany, Ghana, India, Indonesia, Iran, Ireland, Israel, Italy, Japan, Kazakhstan, Macedonia, Mexico, New Zealand, Nigeria, Norway, Pakistan, Philippines, Poland, Portugal, Republic of Korea, Romania, Saudi Arabia, Slovenia, South Africa, Spain, Sweden, Switzerland, Turkey, United Kingdom and United States. Participants were academics (33%), PhD and Master students (29%), researchers (26%), and professionals coming from government institutions and private industry (9%).
The International Organizing Committee consisted of Cristian Gatu (IASC-ERS Chairperson, Romania), Sara Taskinen (IASC-ERS Scientific Secretary, Finland) and Luis Firinguetti-Limone (IASC Webinar Coordinator, Chile). Katie Junasova, Junior Webmaster at the International Statistical Institute, provided support with the organization and with the GoToWebinar platform, and Juergen Symanzik, President of IASC, helped with organizing the Webinar.
The webinar course was supported by the European Regional Section of the International Association for Statistical Computing (IASC-ERS), the International Association for Statistical Computing (IASC), and the International Statistical Institute (ISI).
Objectives of the IASC-ERS School on Computational Statistics and Data Science
- To spread the knowledge base and advances in Statistical Computing in Latin America and the world,
- To provide an overview of the state-of-the-art of the ongoing research in computational statistics,
- To provide an overall perspective of the application of computational statistics in data science problems,
- To present applications where computational statistics have been crucial to solve problems in real-life applications, and
- To increase the number of researchers and practitioners in computational statistics and data science.
