SiDOR research group and the Department of Statistics and Operations Research of the Universidade de Vigo organise the Workshop on ROC Analysis and Related Topics, to be held in Vigo on January 23 and 24, 2025. International experts will meet in Vigo to share their knowledge and present their current contributions and lines of research, including estimation and inferential methods for ROC curves, covariate modelling in the ROC context, evaluation of markers, assessment of classification procedures, selection of cut-off points, etc.

Everybody is welcome to attend! Attendance is free of charge, but registration is required.

Organized by: SiDOR Research Group and Department of Statistics and OR, Universidade de Vigo

Where: Auditorium of the Escola de Enxeñería Industrial - Sede Cidade, Vigo (Address: Rúa Torrecedeira 86, 36208 Vigo, Spain) [map]
