Version 12 is the current development process. Estimated delivery date is fall 2008; although no promises are being made. Paying jobs get first priority...
Matrix to Coordinates 1.0
This application will take any N x N matrix and create a coordinate system (Reimmann space) based on similarities of the objects. The resulting "coordinates" work such that the closer two objects are the more similar they are.
Although the program will handle any size data your system memory will allow; the calculation time is rather slow on matrixes larger than 250.
Other problems exist that will be corrected in future versions when the MDS algorithm used is replaced with a better one. At this time you cannot compare 2 spaces created by this algorithm because the algorithm looks for best fit without comparison considerations. Results in one may be transposed on the other suggesting a major difference when in fact they are the same. A "rotator" is necessary; but not available at this time.
The download is available (Java application) with the usage information built in as a help menu. You should read about how to expand the memory space used by java if you plan on using larger matrixes as they will have out-of-memory errors.
Descriptives & Percentiles 1.0
This program was written to take very large sets of data and create descriptives (means, medians, modes, etc.) and percentile distributions.
This was to answer for the limitations on Excel 97/2000, SPSS student version and other programs. Excel 2007 has fixes for row/column limitations; SPSS has more expensive version to handle it; Matlab and SAS are avalable too.
In the end it took me a few hours to do what would have cost a few hundred dollars; and I only needed D&P. This program is avialable for those who are in the same boat; or just want to play.

Zipf 1.0 - Text Analysis / Clusters
Although the text read / process is slow (future versions will fix this problem), the program will provide cluster analysis and frequency distributions for bodies of text with adjustable parameters such as window and slide size. Data read is UTF8 compliant for multilingual support.

Information Dissemination ABM 1.0
This agent based model program is the early stages of an attempt to identify patterns of information dissemination through social networks. The purpose is to see if placement of message within a network based on parameters of the individuals will influence the saturation percentage and time to saturation vs. using a complete system blast model. Although system blast will reach everyone, the low credibility of the sender results in high deletion without opening/reading. Can open/read saturation be manipulated utilizing high credible sources (members of the network) as starting points for information distributions?
