In their own words
gretl
gretl is a free, open-source desktop package for econometric analysis, available for Linux, macOS, and Windows. It includes statistical tests and regression models, with estimators such as least squares, maximum likelihood, GMM, and regularized methods including LASSO, Ridge, and elastic net. Time-series tools cover ARIMA, GARCH-type models, VARs, VECMs, unit-root and cointegration tests, and the Kalman filter. It also supports panel-data estimators and limited dependent-variable models, including probit and dynamic panel methods based on GMM. Users can script in hansl and export models as LaTeX tables or equations. Data formats include CSV, Excel, OpenDocument, Stata, SPSS, EViews, and others. gretl exchanges data and results with GNU R, GNU Octave, Python, Julia, Ox, and Stata, and supports machine learning via LIBSVM and mixed time-series frequencies via MIDAS. It is distributed under the GNU GPL, which permits redistribution and modification. The maker notes its statistical-method coverage is less comprehensive than GNU R's.
