23–25 February 2021
The Latin American Regional Section of the IASC, the IASC-LARS School on Computational Statistics and Data Science, the IASC and the ISI held a second and successful IASC-LARS Webinar on Computational Statistics and Data Science. The webinar course “Geostatistical Functional Data Analysis” was team-taught by Professors Martha Bohorquez and Rubén Guevara from Universidad Nacional de Colombia, Colombia, from February 23-25, 2021. The course had one collaborator, Juan Guevara from Universidad Nacional de Colombia.
One hundred and eighty-five students completed their registration form on the IASC webpage. Of these 185 students, 71 attended the course. One hundred and thirty-eight students pre-registered for the course on the GTW platform. From now on, we will centralize student enrollment and data collection on the GTW platform. The course was attended by 84 students, 71 students submitted their registration forms, 53 (63%) students attended on 2 or 3 days. Participants came from 23 countries, from Latin America –Brazil, Chile, Colombia, Costa Rica, México, and Uruguay and from countries as far as away as Algeria, Germany, Ghana, India, Indonesia, Italy, Kenya, Nigeria, Pakistan, Palestine, Philippines, Rwanda, South Africa, Tanzania, Turkey, and the USA. Most of the students were undergraduate, master and PhD students (38%), also attending academics and researchers (38%), and professionals coming from government institutions and private industry, 18% of the students were female.
The International Organizing Committee consisted of Alba Martínez-Ruiz IASC-LARS Scientific Secretary (Chile), David Muñoz-Negron IASC-LARS Chairperson (Mexico), and Luis Firinguetti-Limone IASC Webinar Coordinator & Webinar Host (Chile). Katie Junasova, Junior Webmaster at the International Statistical Institute, provided support with the organization and the GoToWebinar platform.
The webinar course was supported by the Latin American Regional Section of the International Association for Statistical Computing (IASC-LARS), the International Association for Statistical Computing (IASC), the International Statistical Institute (ISI), and the Statistical Capacity Building Program.
