IPRFILE= change codes for blocks of persons and items |
IPRFILE= enables rectangles of item and person observations to be changed based on their data codes. This is done after reading in the data files and performing EDFILE= (if specified).
IPRFILE= file name |
file containing details |
IPRFILE= file name + file name + ... |
multiple files |
IPRFILE = * |
in-line list |
IPRFILE = ? |
opens a Browser window to find the file |
IPRFILE= cannot add extra items. Please increase NI= to add extra items. Please specify the highest person beyond those in the data file by means of EDFILE=.
Several selections and recodings can be specified. An observation is recoded according to the first selection that it matches.
The format is:
IPRFILE=* (or IPRFILE= filename) |
item-person-recode sublist or file |
#ITEMS |
start of item list (if omitted, select all items) |
Item number |
select this item |
Item number - Item number |
select this range of items |
- Item number |
exclude this item from this selection |
- Item number - Item number |
exclude this range of items item from this selection |
"Item selection value" |
select items using ISELECT= values, in quotation marks |
- "Item selection value" |
exclude these items |
#PERSONS |
start of person list (if omitted, select all persons) |
Person number |
select this person |
Person number - Person number |
select this range of persons |
- Person number |
exclude this person from this selection |
- Person number - Person number |
exclude this range of persons item from this selection |
"Person selection value" |
select persons using PSELECT= values, in quotation marks |
- "Person selection value" |
exclude these persons |
#RECODE="codes" |
a string of codes which align with the CODES= codes, and indicate the new code values. If a code in #RECODE= is not in CODES=, then it is interpreted as "change that valid code to missing data". |
#MISSING="code" |
this is the code in CODES= to replace "missing-data" in the selection. If this code is not in CODES=, then missing-data in the selection continues to be missing-data. |
# |
next selection begins (if any) .... |
#ITEMS |
start of list for items and persons not selected yet |
...... |
|
#RECODE="codes" |
list of codes for the second selection |
# |
next selection begins (if any) .... |
#ITEMS |
start of list for items and persons not selected yet |
..... |
|
* |
end of IPRECORD= |
Example 1: Convert all responses to items 3 and 7-10 by persons 4 and 13-22 into missing (not administered) data. Other missing responses are to be treated as incorrect.
NI = 16 |
; 16 item test |
CODES = ABCDM |
; the data are multiple-choice responses |
IPRFILE = * |
; start of rectangular recode |
#ITEMS |
; list of items to select |
3 |
|
7-10 |
|
#PERSONS |
; list of persons to select |
4 |
|
13-22 |
|
; CODES = ABCDM |
; this comment is a reminder of the CODES= |
#RECODE = MMMMM |
; A,B,C, D will all be converted to invalid code |
* |
|
IREFER = CBADBACDDCCABDBA |
; same as scoring key (for convenience) |
; CODES = ABCDM |
; comment: another reminder |
IVALUEA = 1000M |
; A scored 1. M scored "M", non-numeric, "missing, not administered" |
IVALUEB = 0100M |
; B scored 1 |
IVALUEC = 0010M |
; C scored 1 |
IVALUED = 0001M |
; D scored 1 |
MISSING-SCORED = 0 |
; all responses not in CODES= scored 0. |
Example 2: Convert all "C" responses to items 3 and 7-10 by persons 4 and 13-22 into "A".
Convert all "C" responses to the other items by persons 4 and 13-22 into "B".
Convert all other "C" responses into "D".
CODES = ABCD |
; valid data codes |
IPRFILE = * |
; start of rectangular recode |
#ITEMS |
; list of items to select |
3 |
|
7-10 |
|
#PERSONS |
; list of persons to select |
4 |
|
13-22 |
|
; CODES = ABCD |
; this comment is a reminder of the CODES= |
#RECODE = ABAD |
; C is converted into A |
# |
; end of this recode: start of next recode |
; #ITEMS |
; commented out: applies to all items |
#PERSONS |
|
4 |
|
13-22 |
|
#RECODE = ABBD |
; C is converted into B |
; #ITEMS |
; commented out: applies to all items |
; #PERSONS |
; commented out: applies to all persons |
#RECODE = ABDD |
; C is converted into D |
* |
Example 3: Select everyone with a person label beginning "A". Make their responses to items with labels starting "Z" into missing data.
CODES = ABCD |
; valid data codes |
IPRFILE = * |
; start of rectangular recode |
; #ITEMS |
; commented out - all items |
"Z" |
;Item labels starting Z |
#PERSONS |
; list of persons to select |
"A" |
; person labels starting A |
; CODES = ABCD |
; this comment is a reminder of the CODES= |
#RECODE = .... |
; All responses made missing. |
