EXAMINE <options> ;
You use the EXAMINE statement to display the characteristics of a selected design. By default, the EXAMINE statement lists certain measures of design efficiency for the best design. (See the section Output.) The following options can be used to modify the output:
- DESIGN
-
lists the actual points in the selected design. Designs are ordered by the value of the efficiency criterion that is being optimized. Thus, a design-number of 1 corresponds to the best design found, a design-number of 2 corresponds to the second best design, and so on. By default, the first design (design-number = 1) is examined. You can select a different design to be examined by using the NUMBER= option.

INFORMATION
INFO
I - NUMBER=design-number
-
selects a design to examine by specifying its design-number.
-
VARIANCE
VAR
V -
lists the variance matrix
for the parameter estimates for the selected design.
For details on design efficiencies see the section Design Efficiency Measures.
If you use the OPTEX procedure interactively, you must enter the options for every EXAMINE statement. For example, the following statements list default information and the design points for the best design but only default information for the second-best design:
examine number=1 design; examine number=2;
The following statements list default information and design points for both the best and second-best designs:
examine number=1 design; examine number=2 design;
