Additional Facets specifications can be placed in separate text files, and then included with your specification file. This is done with the specification:
% include filename
which can be anywhere in the Facets specification and data files, and can also be nested.
Example:
Standard format: Knox Cube Test
Using %include files:
Title = Knox Cube Test (Best Test Design p.31) ; the report heading line
Facets = 2 ; two facets: children and items
Positive = 1 ; for facet 1, children, higher score = higher measure
Noncenter = 1 ; only facet 1, children, does not have mean measure set to zero
Pt-biserial = Yes ; report the point-biserial correlation
Vertical = 1*,1A,2N,2A ; show children by distribution and gender (sex), taps by number and name
Yard = 112,4 ; Vertical rulers 112 columns wide, with 4 lines per logit
Model = ?,?,D ; elements of the two facets interact to produce dichotomous responses
; log(Pni1/Pni0) = Bn - Di
; Bn = ability of child n, Di = Difficulty of item i,
; Pni1 = probability that child n on item i is scored 1.
Labels =
%labels.txt
* ; end of item labels
Data = ; no data file name, so data follows immediately in this file
1 ,1 ,1 ; child 1 on item 1 scored 1 (blanks are ignored)
1 ,2-18,1,1,1,1,1,1,0,0,0,0,0,0,0,0,0,0,0 ; child 1 on item 2 scored 1, on item 3 scored 1, etc to item 18

35,1-18,1,1,1,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0 ; child 35 scored 1 on items 1-3, 0 on items 4-18

1-17 = Boy,,1 ; Pretend boys, in group 1, are numbered 1 through 17.
