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

^      ^ ^         ^           ^

Col. 1      8 10        20          32

 

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
