Usort sort order of unexpected responses = u

Unexpected observations (with standardized residuals greater than Unexpected=) are listed in Table 4. Usort= controls the order in which the unexpected observations are listed.

 

 

Example 1: In Table 4, it is often useful to sort the unexpected residuals by their facet location and size. Sort the residuals by Facet 1 major, Facet 2 minor and then Facet 3.

Usort=1,2,3

 

Multiple sorts and multiple listings of the residuals are obtained by placing each sort order in (). Produces two listings, one sorted by Facet 2 major, the other sorted by Facet 3.

Usort=(2,1,3),(3,2,1)

 

Example 2: Persons are facet 1, items are facet 2 and judges are facet 3. We want to investigate the judges one at a time, paying attention to the most unexpected residuals for each item in Table 4, then identify grossly unexpected person ratings:

Usort = (3,2,u),(u,1)

Unexpected= 3 ; only for very unexpected ratings
