A different kind of network analysis program. FATCAT works with categorical who-to-whom matrices, in which you select a variable that describes nodes to determine the categories for rows (who) and another one to determine the categories for columns (whom). FATCAT uses two files of data at once -- the "Index" file describes nodes and the "Link" file describes links between pairs of nodes. The program is interactive and menu-driven, it provides context-sensitive on-line help. The latest version (4.2, September 1993) uses an intelligent graphics routine to make graphic representations of two-dimensional crosstabulation tables, called "panigrams", which make the information contained in the rows and columns of numbers and percentages immediately evident at a quick glance. It can print to PostScript (color) or Epson-compatible dot-matrix printers. In Windows you can use the clipboard to insert graphical results into your favorite word processor. FATCAT can deal with networks having up to 32,000 nodes, 50 variables, and an almost unlimited number of links. Documentation is on-line.
