gretl 2026a, released by the gretl team, is a cross-platform statistical package purpose-built for econometric analysis and is written in high-performance C. Targeting economists, policy researchers, social-science methodologists, and university instructors, the program provides a full workflow for time-series, panel, and cross-section data: data import from formats such as CSV, Excel, RATS, Stata, SPSS, and ODBC; scriptable or menu-driven model estimation of OLS, IV, GMM, VAR, VECM, ARIMA, ARCH/GARCH, limited-dependent-variable, and count models; built-in hypothesis testers, forecast routines, and bootstrap resampling; integrated graphing engine for publication-quality scatter, line, and residual plots; and dynamic report generation that exports results as LaTeX, PDF, or RTF. The interface is localized to more than fifteen languages, and the installed package ships with extensive downloadable add-ons and a searchable, scriptable function library, allowing users to replicate textbook exercises or run large-scale empirical studies on Windows, macOS, and Linux without additional licensing costs. Since its first public release the software has evolved through six major versions, each expanding the estimation repertoire, improving numerical accuracy, and tightening GNU R and Ox connectivity for advanced scripting. gretl is available for free on get.nero.com, where downloads are delivered through trusted Windows package sources such as winget, always offering the latest build and supporting batch installation of multiple applications.
