XploRe

XploRe is the name of a former commercial statistical software, developed by the Berlin-based company MD * Tech, which is freely accessible but today. The software and the source code of the program, is available on the website. The current version number is 4.8, the software will not be developed any further. The user interacts with the software via the XploRe language, ajar to C programming language. Individual XploRe programs, called Quantlets are summarized in libraries, Quantlibs.

Functions

Apart from standard functions for single and multidimensional data analysis, the focus of the algorithms provided by XploRe lies in the non- and semiparametric statistics and financial market statistics. So XploRe provides functions for

• Kernel density estimation (Kernel Density Estimation ) and regression (kernel regression)
• Single index models
• Generalized Linear and Additive Models ( GLM and GAM)
• Value at Risk ( VaR) and Implied volatility ( implied volatility )

XploRe Quantlet client

In addition to a local installation there is the possibility to run XploRe as a Java applet in the browser with the XploRe Quantlet client. The applet passes the user input over a TCP / IP based communication protocol to a XploRe Quantlet server, which performs the necessary calculations and sends back to the client.

This technology is also used to enrich electronic books with interactive examples.
