MultiNet is a data analysis package
that can be used for ordinary data (in which you have a file that has one line
of data for each case) and for network data (in which there are two files --
the "node" file describes the individuals and the "link"
file describes the connections between individuals).
Note: check back periodically
if you are interested in news about MultiNet.

This version is different from earlier versions in several ways:
- The eigen analysis routines have been completely re-written so they can
handle networks with more than 5,000 nodes. If your network is larger than
that -- say, 20,000 or 50,000 -- write to us and see what we can do.
- The graphic display for spectral analysis can now show strength and direction
of links and node attributes.
- The program can read data in comma-delimited format.
- It can use any node variable for the z-axis in the display of graph spectra
- It does more kinds of transformations and recoding on variables
- It has improved checking for errors in the data
- It has improved, prettier, graphic displays for spectral analysis

Note: Earlier versions of MultiNet are no longer supported.
MultiNet 4.0 for Windows differs from the 2000 version in several ways:
- It was written with a new compiler that is optimized for Windows.
- It has a variety of new types of analysis and display for in-depth exploration
of graph spectra
- It has a graphic display for results of p* analysis that shows missed, correctly
predicted, and falsely predicted links.
- All graphic displays can be resized by resizing the MultiNet window. This
also resizes the images you get when you tell the program to save the graphic
that's on the screen.
- The graphic display for spectral analysis can show node labels and direction
of links; you can redefine the origin for rotation; you can select a region
of the network by drawing a rectangle with the mouse; and more...
MultiNet 3.0 for Windows will be available here before the end of September, 2000. It is different from the 1999 version in several ways:
- It was written specifically to run in Windows (95, 98, NT, etc.). The screen layout looks like the layout for most Windows programs, with a menu bar across the top of the window.
- It is easier to install and run.
- It can export ASCII files that contain any new variables created by recoding, partitioning, or defining.
- The eigen analysis routines have been completely re-written so they can handle networks with up to 5,000 nodes. The previous version could only do 300.
- It does p* analysis on networks with up to 5,000 nodes. It is not a pre-processor. (You do not have to upload your results to SPSS, BMDP, SAS, or any other program.) It does the entire analysis and produces a graphic representation of the results.
- It can find components (strong or weak).
- It can prune the network -- identify the ends of tree structures and create a new link variable that allows you to analyze the network minus the trees.
- It can create a version of the network minus the self-loops -- the entries on the diagonal.
- It has several additional new features.
note: The graphics on the rest of this page are for the 1999 version.
MultiNet 2.11 (1999 version, updated May 9, 1999) is no longer available. It was different from the 1997 version in four ways:
- It produces .bmp (Windows bitmap) instead of .dm (dot matrix)
files for graphic displays. It will also produce .ps (PostScript) files if
you request them.
- The eigen analysis routines have been modified so they can handle
networks with up to 300 nodes. Previous versions could only do 90.
- The new version will run until the end of 1999. Some features of the 1998
version will not work after the end of 1998.
- The new version is easier to install. We have added .pif
files for Windows 95.

In the works...
sparse matrix methods for eigen decomposition will increase the size of networks
that can be examined with these methods;
ability to save ASCII files that contain any new variables created by recoding,
partitioning, or defining;
ability to import space-, tab-, or comma-delimited files as well as the fixed-format
approach now used;
ability to import UCINET or KRACKPLOT files;
the dot matrix output option will be replaced with .bmp or .gif format for
improved interactivity of graphic display for spectral analysis;
ability to perform multidimensional scaling methods on data other than adjacency
multivariate ANOVA and regression analysis;
log linear analysis;
graph theoretic measures
