DATASET subcommand (SPATIAL ASSOCIATION RULES command)

The DATASET subcommand identifies the data sources used in the analysis. The datasets are defined in a map specification file created by the SPATIAL MAPSPEC command.

  • You can specify multiple DATASET subcommands for multiple data sources.
  • Only one DATASET subcommand can specify event data.
DATAID=id
The IDENTIFIER value of the dataset, specified on a DATA subcommand of the SPATIAL MAPSPEC command.
  • If EVENTDATA=YES and more than one data source provides event data, you can specify multiple ID values .
KEEP=fieldname (id id [id...] [type] [measurement level]) fieldname...
Required for multiple event data sources, KEEP creates a single data source from the different data sources. For each field, specify the datasets that contain that field.
ALL
ALL can be used in place of a list of dataset ID values. This keyword includes all fields from all datasets specified on the DATAID keyword.
STRING | NUMERIC
You can optionally specify the data type as STRING or NUMERIC. Data type for each field must be the same in all datasets. The type specification on KEEP treats all instances of the field as the same type. If a type keyword is specified, you must also specify the measurement level.
NOMINAL | ORDINAL | SCALE
You can optionally specify the measurement level as NOMINAL, ORDINAL, or SCALE. This keyword must be preceded by a type keyword. SCALE cannot be specified with STRING.
PREDICTIONS=fieldlist
Specifies the fields that are predictions in the rules.
  • For multiple event data sources, all fields specified for PREDICTIONS must also be specified on KEEP.
  • Fields specified as predictions can also be specified as conditions.
CONDITIONS=fieldlist
Specifies the fields that are conditions. Fields specified as conditions can also be specified as predictions.
BINEXCEPTIONS=fieldname(value list); fieldname(value list);...
For the specified continuous fields, overrides the AUTOBINNING setting and uses the specified list of cut points for binning.
  • The value list is enclosed in parentheses.
  • Specifications for multiple fields are separated by semi-colons.
AGGEXCEPTIONS=fieldname(MEAN|MEDIAN|MODE|SUM|HIGH|LOW); fieldname...
For the specified fields, overrides the aggregation method specified on the AGGREGATION subcommand and uses the specified method.
  • The method name is enclosed in parentheses.
  • Specifications for multiple fields are separated by semi-colons.
