Abstract
The complex mathematics of principal component analysis makes the use
of software indis-pensable for the analysis of repertory grids. GridLab
is a new software package running under Windows which supports the user
in various tasks involved in the definition, editing, com-parison and visualisation
of repertory grids. GridLab was developed in a modern object-oriented programming
language to ensure high performance and portability: The software offers
a graphical user interface that enables even non-experts to quickly edit
and analyse rep-ertory grids. One design principle was to facilitate data
entry. For instance, frequently used elements and constructs can be defined
as a template and loaded by one mouse click. It is pos-sible to insert
predefined elements into the definition of the grid by drag-and-drop.
GridLab originated from the study of self-identity plots, so that the
analysis of such plots is one particular strength of the software. Other
features are principal component analysis (full compatible to INGRID),
cluster analysis and grid comparison (in preparation). Results can be displayed
and printed as high-resolution graphics (even 3D). All data and graphics
can be exported easily into various windows applications such as word processors,
spread sheets or software packages' for statististics.
