A many-facet flat file with multiple raters per line |
Here are the ratings of creativity of junior scientists by three senior scientists (Guilford). The file is in a standard MS-DOS file called "GUILFDAT.txt":
Anne 3 7 7 5 7 5 2 8 7 5 7 2 1 9 7 5 8 5
Chris 1 3 3 3 7 1 3 3 5 5 5 5 2 4 5 3 6 6
David 3 5 3 3 3 1 2 5 6 4 5 5 1 7 3 1 3 3
Edward 2 2 4 3 2 3 3 9 7 7 7 7 1 9 7 7 8 5
Fred 3 3 3 3 5 3 1 3 5 3 5 1 2 4 4 6 4 2
George 2 3 3 5 5 4 1 7 7 5 5 5 3 7 7 7 5 7

Each line of data file has the following description:
Column Facet Description
1-6 Subject Junior scientist's name
8 Rater Rater number (1-3)
10-18 Item Ratings of items 1-5
20 Rater Rater number (1-3)
22-30 Item Ratings of items 1-5
32 Rater Rater number (1-3)
34-42 Item Ratings of items 1-5
The keyword commands required to reformat this for Facets are in file GUILFkey.txt:
; File: GUILFkey.txt
; This converts a many-facet flat file with multiple raters per line to Facets format
$Input = GUILFDAT.txt
$Output = GUILFFAC.txt ; Facets specifications and data
$Facets = 3 ;subject, rater, item
; Output specification lines for FACETS:
$Spec = "Title = Creativity"
$Spec = "Positive = 1 ; subject ability"
$Spec = "Noncenter = 1 ; subjects float"
$Spec = "Output = GUILFOUT.txt ; the FACETS output file"
$Spec = "Models = ?,?,?,R ; the Rating (or partial credit) scale"
; Define the Facet labels
$Flabel = 1,"Junior scientist"
$Flabel = 2,"Senior scientist"
$Flabel = 3,Item
; Define the element labels in terms of where they are in the data records:
; For facet 1, the label is the subject name
$Label = 1,,$S1E6
; Set up pointer in record to first set of ratings
Pointer = 8
; Extract three sets of ratings
$Do = 3
; For facet 2, the rater id is in the record
$Label = 2,$S(Pointer)W1
; Set up item number reference
Item = 1
; Extract 5 item ratings
$Do = 5
; Reference the item number
$Label = 3,Item
; Extract the rating - compute its position
$Rating = $S(Pointer+(Item*2))W1
; Advance to next rating
Item = Item + 1
; Do ratings 5 times
$Again
; Advance to next rater
Pointer = Pointer + 12
; Do this 3 times
$Again
The resulting Facets specification file is GUILFFAC.txt:
; FACFORM Version No. 1.24
; Run on 10-05-1994 12:05:22
; from Keyword file: GUILFkey.txt
Facets = 3
Title = Creativity
Positive = 1 ; subject ability
Noncenter = 1 ; subjects float
Output = GUILFOUT.txt ; the FACETS output file
Models = ?,?,?,R ; the Rating (or partial credit) scale
Labels =
1,Junior scientist
1=Anne
