compares up to 100 different HAMLET **matrices** using Carroll and Chang's
(1970) Individual Differences Scaling,
as an alternative to **PINDIS**.
These should all have been produced using the same search list,
and be of the same size, or an error will be indicated and the
matrix selected will be ignored.

**INDSCAL** provides internal metric analysis of
a set of dis/similarity matrices in terms of a weighted distance
model, such that each "subject" (or text source) has a set of
dimensional weights which systematically "distort" the group
stimulus space.

- First select a series of matrices by clicking on their names in the file list window. This will add the names of the files selected to the right-hand window. (Note that all windows are resizeable.)
- Then click on the
**Run INDSCAL**button to execute the procedure. The results will be displayed in graphic form. It is possible to switch the display between the**subject space**, representing comparisons between the matrices selected, and the**group space**, which shows the corresponding search list items as reflected by combining all of the individual matrices. SUBJSTAT provides an appropriate arc-distance measure for the analysis of the significance of distances between items in the group space coordinates produced by INDSCAL
