XploRe - the statistical computing environment

XploRe is a computational environment for data analysis and statistics. It provides a powerful set of statistical methods and is easily extended by the user. XploRe users may offer their computational methods on the net and thereby help in proliferating new technology and statistical methods.

Language

XploRe is a procedural language, i.e., the user writes procedures or functions, like in Pascal or C/C++. In contrast to these languages the declaration of variables is not necessary in order to preserve the character of an interpreter. Furthermore, variables can be collected in list structures, so that it is possible to hold common information of a data set in a single data object. Of course, all the features of an high-level language like recursion, local variables, loops, and conditional execution are available. Dynamic link calls are possible and remote procedure calls (RPC) to other software enlarge the XploRe environment.

Platforms

The data are represented as C++ classes. All numerical algorithms, the administration of the symbol tables and of the flow control, as well as most parts of the graphic subsystem are implemented in C++, too. XploRe is developed for Windows, Solaris, HP-UX, SGI, and Linux. The XploRe Java Client and Server engines are available for these platforms as well. A trial version of XploRe may be downloaded for free.

Networking

The APSS (auto pilot support system) is available in HTML and can be used with common browsers. The Java interface allows net based computing from everywhere in the web. The Java interface is a full XploRe GUI with local generation of graphics and data handling. It is the ideal tool for web based teaching and proliferation of new statistical techniques.
