The ROW list is used when either the sparse or the dense format of side constraints is being used. SAS variables in the ROW list have values that are constraint or special row names. The SAS variables in the ROW list must have character values.
If the dense
data format is used, there must be only one SAS variable in this list. In this case, if a ROW list is not specified, the
CONDATA=
data set is searched and the SAS variable with the name _ROW_ or _CON_ is used.
If the sparse
data format is used and the ROW statement is not specified, the CONDATA=
data set is searched and SAS variables with names beginning with _ROW or _CON are used. The number of SAS variables in the ROW list must not be less than the number of SAS variables in the COEF
list. The ith ROW list variable is paired with the ith COEF
list variable. If the number of ROW list variables is greater than the number of COEF
list variables, the last ROW list variables have no COEF
partner. These ROW list variables that have no corresponding COEF
list variable are used in observations that have a TYPE
list variable value. All ROW list variable values are tagged as having the type indicated. If there is no TYPE
list variable, all ROW list variable values are constraint names.
