Table 3.

Table 3 is the iteration report. The final line of this is crucial to a successful analysis. It should read:

Subset connection O.K.

 

If you Facets reports disjoint subsets, then you have more than one set of data that are not linked and cannot be analyzed on the same measurement scale.

 

 If you are interested in the technical aspects of the iteration report and convergence, refer to the technical documentation available from Winsteps.com or to Szabo's book Applying item response theory in language test item bank building (2008, Peter Lang).
