Mathematical and statistical programming language.
GAUSS 6.0 includes a number of new features and enhancements designed to increase speed, power and functionality of GAUSS. The new version of GAUSS includes additional support for string arrays, more functions support multi-dimensional arrays, and a faster multi-column sort, as well as new Run-Time Library procedures and structures and new GUI features in GAUSS for Windows.
What's new
New features and enhancements include:
| • | New Run-Time Library procedures and structures |
| • | New GUI features in GAUSS for Windows |
| • | Many more functions support multi-dimensional arrays |
| • | Faster inverse and linear equations solver |
| • | The commands 'selif' and 'delif' are now intrinsics, making them up to 4 times faster |
| • | Additional support for string arrays |
| • | Faster multi-column sort |
New Run-Time Library procedures and structures
| • | New versions of the unconstrained optimization and equation solution procedures called 'QNewtonmt' and 'eqSolvemt' that use structures |
| • | 'QNewtonmt' uses the new 'gradmt' and 'hessmt' procedures; an analytical gradient procedure can be provided which computes a subset of the derivatives and 'QNewtonmt' will compute the remaining derivatives numerically |
| • | Also new are functions for computing moving averages and combinations, 'movingAve' a simple moving average, 'movingaveWgt' a weighted one, and 'movingaveExpwgt', an exponentially weighted one; these functions employ sparse matrices for very rapid calculations on large matrices |
| • | New combination functions compute all combinations of a sequence of integers taken k at a time; 'combinate' returns a matrix of these integers, and 'combinated' stores them in a GAUSS data set |
New GUI features in the Windows version
| • | Source View Window - This is a dockable dialog bar that gives the GAUSS user instant access to all source files and symbols in all active libraries. Capabilities include search, instant edit, and symbol/file properties. |
| • | Error Window - Allows the GAUSS user to click on compiler errors and go right to the source where the problem occured, avoiding the hassles of searching through pages of files to find them. |

Analisi statistica
The GAUSS Mathematical and Statistical System is a fast matrix programming language widely used by scientists, engineers, statisticians, biometricians, econometricians, and financial analysts.
Designed for computationally intensive tasks, the GAUSS system is ideally suited for the researcher who does not have the time required to develop programs in C or FORTRAN but finds that most statistical or mathematical "packages" are not flexible or powerful enough to perform complicated analysis or to work on large problems.
Whatever mathematical tool or language you are now using, you'll find that GAUSS can greatly increase your productivity!
Comprehensive Environment for Modeling and Analysis
GAUSS is a complete analysis environment suitable for performing quick calculations, complex analysis of millions of data points, or anything in between. Whether you are new to computerized analysis or a seasoned programmer, the GAUSS family of products combine to offer you an easy to learn environment that is powerful and versatile enough for virtually any numerical task. Since its introduction in 1984, GAUSS has been a standard for serious number crunching and complex modeling of large-scale data.
Worldwide acceptance and use in government, industry and the academic community is a firm testament to its power and versatility. The GAUSS System can be described several ways: It is an exceptionally efficient number cruncher, a comprehensive programming language, and an interactive analysis environment. GAUSS may be the only numerical tool you will ever need.
Interactive and Fast
For simple problems GAUSS provides a fully interactive environment for exploring data, creating scenarios and analyzing results. For more complex tasks, you can write programs and save them to disk. GAUSS is exceptionally fast, providing performance comparable to compiled C or FORTRAN programs. And unlike other math packages, GAUSS's speed is equally impressive when working with problems of very large scale.
Straightforward and Efficient
While many GAUSS users never find a need to program extensively, for those who do, GAUSS provides a natural and logical environment that is easy to learn and powerful to use. At the core of GAUSS is an efficient programming language adequate for doing even the most sophisticated analysis. The basic unit of analysis in GAUSS is a matrix, resulting in a syntax closely resembling common mathematical expressions. Since matrix operations are assumed, most of the looping required by other languages is eliminated.
The Data Translation Loop allows transformations on variables in a data set by directly using the variable names in expressions. This streamlines data transformations and makes for shorter, more readable programs. GAUSS's Source Level Debugger greatly simplifies program development. With all of the features you would expect in a dedicated debugging system, you can quickly identify and solve program logic errors at run time.
Additionally, GAUSS handles complex numbers automatically and seamlessly. You don't have to keep track of the real and imaginary parts of a matrix. Complex numbers are handled automatically, that greatly simplifies programming for engineering and other tasks that require working with complex numbers.
The Language
As a complete programming language, the GAUSS system is both flexible and powerful. Immediately available to the GAUSS user is a wide variety of statistical, mathematical and matrix handling routines.
GAUSS can be used either interactively for short one-off commands or by creating large programs consisting of several files and libraries of functions, or anything in between.
Visualization and Presentation
GAUSS's high resolution Publication Quality Graphics gives you powerful ways to visually analyze your data and present your findings. A wide choice of graphing options are available to you, including 2D, 3D, surface, contour, polar and log graphs, as well as bar graphs, histograms, box graphs and more. Graphs can be placed in individual overlapping or tiled windows on a single page. You can export graphics files in a number of popular formats, including WMF, HP-GL/2, PostScript and EPS formats, for use in page layout and presentation packages, and GAUSS includes support for a wide range of output devices, including most of the latest printers and plotters.
The Tools You Need
GAUSS has over 400 mathematical functions built in, including LINPACK, EISPACK and BLAS routines, factorizations, decompositions, eigenvalues, distributions and equation solving functions, to provide you with all the tools you need to solve your most difficult problems. You can easily customize or add to the GAUSS function library, and optional modules provide access to many other specialized capabilities.
Other important features include: data import/export compatibility with many popular spreadsheets and databases, long period random number generators, built-in functions for efficiently handling sparse data, and a Foreign Language Interface for incorporating your favorite compiled C and FORTRAN programs directly into GAUSS programs.
Available for Windows, Unix, and Linux

GAUSS Data Tool is a stand-alone program for working with GAUSS data sets. GAUSS Data Tool loads the columns of the data sets into a workspace as vectors where they can be transformed or modified using simple intuitive statements. Data sets can also be created by simulation using a variety of models, e.g., probit, logit, GARCH, linear. A new version of a data set can be generated where missing data are replaced by single or multiple imputations from a maximum likelihood extimation using EM algorithm.
