01 · The laboratory

Statistics for
real-world data.

MultLab is part of the Department of Statistics at the Center for Exact and Natural Sciences of the Federal University of Pernambuco.

The laboratory was authorized by UFPE in 2023 as the Multidisciplinary Laboratory for Statistical Modeling, linked to CCEN. Its work connects methodological development, statistical computing and applications across scientific fields.

The research areas presented on this website are an editorial synthesis based on the public research, projects and scientific output of the coordinators and collaborators — not a normative list of official laboratory research lines.
