PSUBTOTAL= columns within person label for Tables 28, 35

This specifies what part of the data record is to be used to classify persons for subtotal in Table 28.

 

PSUBTOTAL= file name

file containing details

PSUBTOTAL = *

in-line list

PSUBTOTAL = $S1W1

field in person label

 

With tab-separated data and the subtotal indicator in a separate field from the Person label, specify the subtotal field as the person label field using NAME1=, then PSUBTOTAL=$S1W1

 

Format 1: PSUBTOTAL = $S..W.. or $S..E.. using the column selection rules.

$S..W.. e.g., $S2W13 means that the label to be shown on the map starts in column 2 of the person label and is 13 columns wide.

 

$S..E.. e.g., $S3E6 means that the label to be shown on the map starts in column 3 of the person label and ends in column 6.

 

These can be combined, and constants introduced, e.g,

PSUBTOTAL=$S3W2+"/"+$S7W2

 

If the person label is "KH323MXTR", the sub-grouping will be shown as "32/XT"

 

Format 2: PSUBTOTAL=*

This is followed by a list of sub-groupings, each on a new line:

 

PSUBTOTAL=*

$S1W1+$S7W2  ; Subtotals reported for person classifications according to these columns

$S3E5   ; Subtotals reported for person classifications according to these columns

*

 

Example: Subtotal by first letter of person name:

 

PSUBTOTAL=$S1W1

TFILE=*

27 ; produce the subtotal report

*

 

Here is a subtotal report (Table 28) for person beginning with "R"

Example: You want an average score for each option on a multiple-choice test.

 

1. Include the item response string in the person label

 

Data record

Fred ABCDE

 

NI = 5

Item1=6

Name1=1

Namelength=10

 

2. Produce subtotals for every item

 

PSUBTOT=*

6  ; corresponds to Item 1

7

8

9

10

...

*

 

3. Specify Table 28

 

TFILE=*

28

*

 

4. Table 28 output is voluminous, but the numbers are there. Do a search for "| MEAN".
