CSPATIALREG Procedure

You can use a BY statement in PROC CSPATIALREG to obtain separate analyses of observations in groups that are defined by the BY variables. When you use a BY statement, the primary input data table (specified in the DATA= option) should be sorted by the BY variables.

BY-statement processing is not supported when the CSPATIALREG procedure runs alongside the database or alongside the Hadoop Distributed File System (HDFS). These modes are used if the input data are stored in a database or HDFS and the grid host is the appliance that houses the data.
