## OUTDESIGN= Data Set

An output data set containing the design matrix is created
whenever you specify the
OUTDESIGN= option in the PROC GLMMOD statement.
The OUTDESIGN= data set contains an observation for each
observation in the DATA= data set, with the following variables:
- the dependent variables
- the FREQ variable, if any
- the WEIGHT variable, if any
- a variable for each column of the design matrix, with
names COL1, COL2, and so forth

If there are BY-group variables or if the pattern of missing
values for the dependent variables requires it,
the single data set contains several design matrices. In this
case, for each of these, the OUTDESIGN= data set also contains
the following:

- the current values of the BY variables, if you specify a BY statement
- a numeric variable, _YPASS_, containing the current pass
of the data, if the pattern of missing values for the
dependent variables requires multiple passes
