PROC PLAN Statement
The PROC PLAN statement starts the PLAN procedure
and, optionally, specifies a random number seed or
a default method for selecting levels of factors.
By default, the procedure uses a random number seed
generated from reading the time of day from the
computer's clock and randomly selects levels of factors.
These defaults can be modified with the
SEED= and ORDERED options, respectively.
Unlike many SAS/STAT procedures, the PLAN procedure does not have a DATA=
option in the PROC statement; in this procedure, both the
input and output data sets are specified in the OUTPUT statement.
You can specify the following options in the PROC PLAN statement:
- PROC PLAN < options > ;
specifies a positive integer less than 231 - 1.
PROC PLAN uses the value of the SEED= option to start the pseudo-random
number generator for selecting factor levels randomly.
The default is a value generated from reading
the time of day from the computer's clock.
selects the levels of the factor as
the integers 1,2, ... ,m, in order.
For more detail, see the "Selection-Types" section and
see the "Specifying Factor Structures" section.
