Delements element type in data = N |
Top Up Down
A A |
Delements= specifies the element identifier in the data file for the Labels= facet.
Format 1: Delements = type |
|
Delements = N |
all element identifiers in the data are element numbers in Labels= |
Delements = L |
all element identifiers in the data are element labels in Labels= |
Delements = B |
all element identifiers in the data can be both element numbers and element labels in Labels=. Element numbers are matched first. If the element identifier does not match any element number for the specified facet, the identifier is matched with the element labels |
Format 2: Delements = Facet number + type, Facet number + type, ... Example: Delements = 1N, 2L, 3B |
|
1N, |
facet 1 element identifiers in the data are element numbers in Labels= |
2L, |
facet 2 element identifiers in the data are element labels in Labels= |
3B |
facet 3 element identifiers in the data can be both element numbers and element labels in Labels=. Element numbers are matched first. If the element identifier does not match any element number for the specified facet, the identifier is matched with the element labels. |
Delements = L or B - Matching element identifiers in the data with Labels= element labels |
|||
Delements= |
When matching an element identifier in the data with element numbers or labels in Labels=, the priority is: |
||
N or B |
1. The identifier in the data is matched with the element number in the facet list |
"7" in the data matches element number "7" for facet 1, so the element number is 7 |
Facets = 5
Labels= 1, Grade level 7= Grade seven * 2, cohort 8= myx21pq * 3, gender facet 2 = boy: male student * 4, activity facet 4 = run * 5, school facet 8= Marymount * Data= 7, x21, boy, run, M, 1 |
L or B |
1. The identifier is an exact match to the segment of an element label specified with S..W.. or S..E. |
Delements = 1LS3E5 or 1LS3W3 "x21" in the data matches "x21" in columns 3,4,5, so the element number is 8 |
|
L or B |
1. The identifier is an exact match to the part of an element label before : (a colon) |
"boy" in the data matches "boy:". so the element number is 2 |
|
L or B |
2. The identifier is an exact match with an element label without a : (a colon) |
"run" in the data matches "run:". so the element number is 4 |
|
L or B |
3. The identifier is a leading-character match with an element label that has no : (a colon) |
"M" in the data matches the leading M in "Marymount", so the element number is 8 |
|
Example 1: in the data, the facet 1 element identifiers are element labels, for facet 2, element numbers, and for facet 3 are element labels. The observations are 0-1 dichotomies:
Labels =
1, Gender
1= Female
2= Male
*
2, Zip code
60601 = Central Chicago
60637 = Hype Park Chicago
...
*
3, Income
1 = Low
2 = Medium
3 = High
*
Data =
F 60637 2 0 ; Female, 60637 Zip code, Medium income, No
M 60601 3 1 ; Male, 60601 Zip code, High income, Yes
Example 2: chess tournament: paired comparisons with element labels
Facets = 3 ; player, player, round
Entered in data = 1,1, 2 ; the players are facet 1, round is facet 2
Models = ?,-?, ?, D
Delements = 1L, 2N ; element identifiers for facet 1 are element labels, for facet 2 are element numbers
Labels=
1, Players
1= John
2= Mary
3= ...
*
2 = Round
1= Monday morning
2= Monday afternoon
3= Monday evening
.....
*
Data =
John Mary 1 0 ; John played Mary on Monday morning. John lost.
