NLMOD Procedure

The ID statement lists one or more variables from the input data table that are transferred to output data tables that PROC NLMOD creates, provided that the output data table contains one or more records per input observation. For example, when you use an OUT= option in the PROC NLMOD statement to produce prediction statistics, ID variables are added to the output data table.

By default, PROC NLMOD does not include all variables from the input data table in output data tables.
