DPF= columns within item label for Table 31 = $S1W1

DPF= specifies the part of the item label which is to be used for classifying items in order to identify Differential Person Function (DPF) - uniform or non-uniform - using the column selection rules. See also DPF Table and DIF and DPF considerations.

DPF= file name	file containing details
DPF= *	in-line list
DPF= $S1W1	field in item label
DPF= MA2	item difficulty levels for non-uniform DPF
DPF= $S1W1 + MA2	item groups

See ISUBTOTAL for format.

See DPF Table 31.

Example 1: Columns 3 and 4 of the item label (between &END and END LABELS) contains content-area code:

DPF = $S3E4 ; start in column 3 and end in column 4 of item label

tfile=*

31 ; Table 31 is DPF Table (or use Output Tables menu)

Example 2: Columns 3 of the item label contains a content code. Column 5-6 have a complexity code. Two independent DIF analyses are needed:

DPF = *

$S3W1 ; content analysis

$S5W2 ; complexity

tfile=*

31 ; Table 31 is DPF Table (or use Output Tables menu)
