A list that can be used to categorize the entries of the list specified in the
List field.
Include Categories *

to specified category values. For example, if you specify {1,4}, the
calculation uses only data points with a category value of 1 or 4.
* For more information on using these inputs, see the example Studying Statistics:
Filtering Data by Categories in the Applications module.
Tip: In any field that requires a list, such as List, Freq, Category List, Include Categories, etc., you can
enter a list name or the list elements themselves. To enter the list elements in the field, simply key in
the elements inside the pair of braces ( {} ) in the field.
Outputs for List
All the statistics outputs are stored to the variable mat1var in the STATVARS folder.
mat1var is a matrix. The first column (c1) contains the descriptor (v, Gx, etc.). The second
column (
c2) contains the calculations. Each additional column of the matrix contains the
output statistics for each corresponding input list. The output statistics are arranged in
the same order as they appear in the output dialog box (the same order as shown in the
table).
See page 113, Correlation Matrix, for an example of how to access the data matrix.
