GAUSS is a fast, powerful, highly adaptive suite of analytical software and tools. Its flexible matrix language, intuitive interfaces and powerful applications enable swift transformation of data and ideas into action. From prototype to production, GAUSS has the tools you need get the job done.

For professionals in data-driven disciplines from finance to physics, GAUSS has long been the go-to source for specialised models, techniques and applications. However, GAUSS is also a comprehensive environment that gives you everything you need to develop, adapt, execute and generate publication quality graphics for virtually any problem or project.

GAUSS is ideal for rapid prototyping as well as complete implementation of a wide range of scientific and business models. All functions and programs can be altered by the user and easily integrated with C/C++, Java, FORTRAN and other environments.

Learn more about the specific strengths GAUSS offers these diverse industries:


  • Efficient data organisation, management, and publication quality presentation.
  • Functions are easily adaptable to fit individual model specifications, making it an ideal program for univariate, multivariate, panel series, cross-sectional and time-series analysis.
  • Includes a quick and reliable maximum likelihood routine.
  • Provides pre-programmed classical regression analysis tools with the framework necessary for implementing modern regression techniques including time-varying parameters, Markov-Switching models, Bayesian analysis and DSGE models.
  • Computation of large datasets and complex models can be done quickly. This, combined with tools for process automation, documentation, and presentation, allow for efficient econometric analysis.


  • GAUSS is equipped with pre-programmed routines for implementing binomial options pricing model to both European and American call and put options.
  • The available GAUSS Fanpac application provides built in commands for complete modelling and analysis of standard finance univariate and multivariate models.
  • Fanpac includes easy to use keyword commands for analysing the complete family of ARIMA, ARCH, GARCH and IGARCH models.
  • Documentation and visualisation of model results is clear, thorough, and easy to interpret and share.
  • GAUSS is capable of efficiently handling large datasets and provides tools for easy data management making it suitable for high frequency data.
  • The combined GAUSS finance procedures along with keyword functions make the platform appropriate for easy updating of results, while simultaneously meeting the needs of specialised models.


  • GAUSS offers a complete set of tools for data organisation, analysis and presentation. Survey data, cross-sectional data and large panel data can easily be easily managed using a number of conditional data selection and sorting tools.
  • GAUSS is equipped to efficiently conduct statistical inference, correlation and regression analysis, and categorical, multivariate, time-series and survival analysis.
  • GAUSS’s standard data analysis can be enhanced with the available Descriptive Statistics MT application which includes methods for analyzing and generating contingency tables.
  • Regression analysis is made easy with available suites of pre-programmed discrete choice and panel series regression tools.


  • GAUSS performs high efficiency modelling and simulation of complex systems of equations using structures, threading and parallel computing.
  • GAUSS provides a complete set of tools for standard and advanced applications of numerical analysis, applied linear algebra, initial and boundary value problems, Fourier analysis and optimisation.
  • Optimization MT application implements wide selection of descent algorithms, step-length methods, and “on-the-fly” algorithm switching. User controlled options allow for model specificity and optimisation flexibility.
