A WINSTEPS input data file

Here is the WINSTEPS data file, KCTDAT.txt, used for analyzing the KCT data.



TITLE='Knox Cube Test (Best Test Design p.31)'











1= 1-4

2= 2-3


(and so on down to)





Richard M 111111100000000000

Tracie  F 111111111100000000


Elsie   F 111111111101010000

Helen   F 111000000000000000


Here is the Facform reformatting file, KCTkey.txt:


; File: KCTkey.txt

; This converts a BIGSTEPS file into a Facets file

$Input = KCTDAT.txt

$Output = KCTFDT.txt


$Facets = 2 ; children and item


; labels for the facets

$Flabel = 1, "Children"

$Flabel = 2, "Tapping items"



Control="Yes" ; we are processing BIGSTEPS control

Itemnum=0  ; no items so far



$If=(Control="Yes") ; Processing control variables

; let's pick out the title and write it to the Facets specifications

$If = ($S1W5 = "TITLE")

$Text = $S1W50 ; output the Title=

; and let's also output the other specifications that Facets needs:

$Text = "Output = kctOUT.txt ;the Facets output file"

$Text = "Models = ?,?,D"


 $If = ($S1W4 = "&END")

  Control = "Names" ; set to read item names



 $If= (Control = "Names")

 ; now look for the item names

$If=($S1W9="END NAMES")

Control="Data" ; set to read the data

; print a message to the screen for information

$Print= "Processing END NAMES"


Itemnum = Itemnum + 1   ; increment the item number

$Label = 2, Itemnum, $S4W20 ; save item number and name



; we are now processing the data - the person name is the identifier

$Label = 1, , $S1W9 ; the element name is person id

; reset item numbering

Item = 0

; now go across the line for as many items as there were names

$Do = Itemnum

Item = Item +1

; the ordinal number of this item

$Label = 2,Item

; the item from its position in the data record: Item 1 in column 11.

$Rating = $S(Item+10)W1 ; output the observation





The resultant Facets file, KCTFDT.txt, is:


; FACFORM Version No. 1.20,  May 4, 1992

; Run on 05-04-1992 12:02:45
