This menu can be used too form a factor from a variate or text data structure.
Data
Specifies the variate or text containing the data.
Save In
Specifies the name of the factor to be formed from the numeric or textual data. If this is left blank,
the original variate or text will be converted into a factor, overwriting the original definition.
Method
This specifies how the groups are to be formed from the data.
Mapping
forms a group for each distinct value of the variate or text.
Ranges
divides the range into categories specified by their end-points.
Quantiles
computes ranges automatically, to form groups of approximately equal sizes.
Ranges
Specifies the boundary values between the groups. To obtain n groups you will need to have n-1 values listed here.
Boundaries
Specifies whether the boundary values are included at the upper or lower end of
each group; e.g. if the Ranges are specified as "1.0 2.0 3.0" the value 2.0 can
be assigned to either the group 1.0-2.0 (upper limits) or 2.0-3.0 (lower
limits).
How Many?
Specifies how many groups are required when using Quantiles.
Available Data
This lists data structures appropriate to the current input field. The contents
will change as you move from one field to the next. Double-click on a name to
copy it to the current input field; alternatively, you can type in the name
directly.
Display In Spreadsheet
Allows you to display the results in a spreadsheet. You can select the sheet from
the list of current open spreadsheets or request a new spreadsheet be created.
Note: the number of rows of the spreadsheet must match the length of the results
formed by the calculation, otherwise a new sheet will be used.
