In their own words
BlueSky Statistics
BlueSky Statistics is a data management and analysis application for statistics, machine learning, visualization, quality and process engineering, and Six Sigma work. It runs on macOS and Windows and supports desktop deployment. Analysts can import Excel, CSV, and other files or paste spreadsheet data into its grid. Analysis options include descriptive and inferential statistics, regression, advanced modeling, survival and longitudinal analysis, power analysis, and design of experiments. Quality workflows include measurement system analysis, gage R&R, process capability, SPC charts, tolerance intervals, and reliability analysis. The application is built around R and Python and includes an R editor for custom scripts. Its machine-learning offering lists more than 50 algorithms across traditional and deep-learning model families. Tables and graphs can be copied to Word, Excel, and PowerPoint; output can be saved in BlueSky format, HTML, R Markdown, or LaTeX. Base is free forever. Pro costs $495 a year and adds a commercial license, priority technical support, premium modules, productivity features, and reproducibility features.
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.
