State Space Grids
State Space Grid analysis now part of Mangold Interact analysis package!

State space grids were developed by Marc Lewis and colleagues (Lewis, Lamey & Douglas, 1999) as a way to represent synchronous ordinal time series on a 2-D grid. To make this technique freely accessible, we have developed this web site to distribute a software program, GridWare, that creates state space grids from most ordinal or categorical time series.
