Statsu

Statsu is a cross-platform statistical computing environment designed for data analysis, modeling, and visualization. It provides an integrated workflow that combines data management, statistical modeling, and reporting within a single platform, with an emphasis on reproducibility and extensibility.

Statsu originated in the early 2010s as a collaboration among universities and research laboratories, with the first public release in 2013. It is developed and maintained by the Statsu Foundation, a non-profit organization that oversees governance, licensing, and community involvement.

The environment centers on a unified scripting language called Statsu Script and a rich standard library. It supports data frames, functional pipelines, and declarative model specifications. It includes modules for linear and generalized linear models, mixed-effects models, time-series analysis, survival analysis, clustering, and machine learning. Visualization is built in, offering layered plots and interactive dashboards. The plugin architecture allows third-party extensions; a package manager handles community packages. Statsu can import and export common formats such as CSV, JSON, Parquet, and Excel, and supports notebook-style workflows and reproducible reports that combine code, results, and narrative.

Statsu is used in academia for teaching and research, as well as in industry for data-science workflows in fields such as epidemiology, economics, and engineering. It is valued for its emphasis on reproducibility and transparent versioning, though it is sometimes noted for a learning curve and a smaller ecosystem compared to more established tools, along with occasional performance considerations on very large datasets.
