Guessing elimination

Facets does not have a mechanism for compensating for guessing.

The nearest thing would be to trim the data to remove all responses to items that are too difficult for the person.

1. Do the standard Facets analysis

2. Output the Residual file= to Excel

3. Sort the Excel worksheet on the column Meas.

4. Delete all rows when the Meas is too negative = the challenge is too high, so provoking guessing

5. Construct the trimmed data file, by reaarranging the Excel columns:

Element number for Facet 1 Element number for Facet 2 .... Obs (delete the other columns)

6. Rerun the Facets analysis with Data= the Excel file from 5.
