Gauss, il software per lo sviluppo e la gestione delle statistiche

GAUSS, riferimento storico per il software statistico, è stato utilizzato per quasi 20 anni da professionisti in aree che richiedono elaborazioni statistiche e matematiche su larga scala.
Basato su un linguaggio di programmazione a matrice, Gauss include molti moduli applicativi (scritti in linguaggio GAUSS) per espandere le capacità del software e offre funzioni avanzate specifiche, in particolare per la finanza e l'econometria.

WHY CHOOSE GAUSS?

Gauss is a software combining power and ease of use. It has 4 major assets to carry out your analyses quickly and efficiently:

EXTREMELY FAST SOFTWARE

With more than 450 integrated features, including LINPACK, EISPACK and BLAS libraries, advanced data management tools and complex numbers support, GAUSS considerably simplifies the task of developers.

ADVANCED COMMUNICATION FUNCTIONS

GAUSS can read common formats (Excel, Lotus, Dbase, Paradox ...), and specialized modules enable dynamic access to your data in Excel.

No more acrobatics between applications to access your data! 

THREADING FUNCTIONS

To take advantage of the power of the latest multi-core or multi-processor systems, the Threading functions:

  • ThreadStat
  • ThreadBegin
  • ThreadEnd
  • ThreadJoin

They enable you to compartmentalize your programs into sections that can be run simultaneously. These Threads are part of the same working space and can access and use any previously created global symbols, keywords, and procedures or routines. You can create as many "threads" as you want, which enables you to use all processors available on your hardware.

SAVING TIME WITH THE APPLICATION MODULES

Written in Gauss language, the application modules extend the possibilities of GAUSS:

  • The basic application modules contain most of the necessary functions in statistics, finance and econometrics, saving time during your development
  • Application modules specialized in statistics, finance and econometrics, give you access to high level techniques developed by experts and help you to design your own models

Funzioni

 

GAUSS ™ MATHEMATICAL AND STATISTICAL SYSTEM

The mathematical and statistical system of GAUSS is based on a fast matrix programming language, widely used by scientists, engineers, statisticians, biometricians, econometricians, and financial analysts. Designed for intensive computing, GAUSS is ideally suited for the researcher who does not have the time to develop programs in C / C++ or FORTRAN, and who thinks that most statistical or mathematical packages are not flexible or powerful enough to perform complex analyses or to work on complex problems.

Whatever the mathematical tool or the language you are currently using, you will notice that GAUSS can significantly increase your productivity!

A COMPREHENSIVE MODELLING AND ANALYSIS ENVIRONMENT

GAUSS has a complete analysis environment suitable for performing fast calculations, complex analyses of millions of data points, or anything in between. Whether you are a new user of computer analysis or a seasoned programmer, the GAUSS family of products combines to provide you with a work environment that's easy to understand, powerful and versatile enough to do virtually any digital job.

Since its appearance on the market in 1984, GAUSS has always been a benchmark for large-scale computations and complex data modeling. The recognition and global use of GAUSS within governments, industries and academic communities are a testimony to its power and versatility. The GAUSS system can be qualified in different ways: an exceptionally efficient calculator, a complete programming language and an interactive analysis environment.



GAUSS might become the only digital tool you will ever need.

INTERACTIVITY AND SPEED

For simple problems, GAUSS offers a fully interactive environment for exploring data, creating scenarios and analyzing results. For more complex tasks, you can write programs and save them to the hard disk. GAUSS is an exceptionally fast tool that offers execution performance similar to that of compiled C or Fortran language. And unlike other math packages, Gauss's speed is even more impressive when working on large scale problems.

SIMPLICITY AND EFFICIENCY

While many GAUSS users will never need intensive programming, for those who do, GAUSS offers a natural, logical and powerful environment which is easy to grasp. At the heart of GAUSS is an appropriate programming language to carry out the most sophisticated analyses.

In GAUSS, the basic unit of analysis is a matrix, resulting in a syntax that closely resembles common mathematical expressions. Since matrix operations are adopted, most of the loopbacks required by other languages are eliminated. 

The Data Translation Loop lets you perform transformations on variables in a data set by directly using the variable names in the expressions. This streamlines data transformations into shorter and more readable programs. The GAUSS Source Level Debugger greatly simplifies program development. With all the features you've come to expect from a dedicated debugging system, you'll be able to quickly identify and troubleshoot programming errors at runtime.

THE LANGUAGE

As a complete programming language, the GAUSS system is both flexible and powerful. A wide variety of statistical, mathematical, and matrix management routines are immediately available to the GAUSS user. GAUSS can be used interactively for short, one-time commands, for creating large-scale programs with multiple files and function libraries, or for anything in between.

VISUALIZATION AND PRESENTATION

GAUSS's high resolution graphics give you powerful ways to visually analyze your data and present your results. A wide choice of graphs is available: 2D, 3D, surface, contour, polar graphs and log, as well as bar charts, histograms, box plot and more. Charts can be placed in individual overlapping or tiled windows on a single page.You can export graphics files in a number of common formats such as JPEG, SVG, PNG, HP-GL / 2, PostScript and EPS, to use them in a layout or presentation software. In addition, GAUSS supports a wide range of output devices.

THE TOOLS YOU NEED

GAUSS comes with more than 450 highly optimized integrated mathematical functions, including LAPACK, EISPACK and BLAS libraries, factorization, decompositions, eigenvalues, distribution and equation solving functions, in order to provide you with all the tools that you need to solve your most difficult problems.

You can easily customize or add them to the GAUSS function library, and optional modules provide access to many other specific capabilities. The GAUSS Run-Time Module (GRTM) lets users and developers share GAUSS applications and compiled files with non-GAUSS end users.


Other important features such as:

  • Compatibility of import / export data with spreadsheets
  • Random number generator for long periods
  • Built-in functions for efficient management of sparse data
  • A foreign language interface to integrate your favorite compiled programs in C and Fortran directly into GAUSS programs

THE PRODUCTS OF THE GAUSS FAMILY

GAUSS Data Tool: a solution for GAUSS data

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, such as: 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 estimation using the EM algorithm.
(Available only for Windows and Linux)

GAUSS Engine: an enterprise solution

Gauss Engine increases the speed and power of GAUSS for applications written in C, C ++, Java, VB or other development environments that support the C API language. GAUSS Engine is a dynamically linked library for compiling and running GAUSS programs from another application. The data is going back and forth between the GAUSS Engine's working space and the application.
The distribution of your GAUSS Engine applications is free of rights.
