Answer / rohit
SAS can be used to generate random numbers. The command
RANUNI is used to generate random numbers from a uniform
distribution ranging from 0 to 1, and the command RANNOR is
used to generate random numbers from a standard normal
distribution. To use the command, we need to specify a
seed. The seed, a numerical value, is placed in parentheses
after the command. If a different numerical value or seed
is specified, the commands will produce a different set of
random numbers. For example, the value produced by
RANUNI(1) is different from the value produced by RANUNI(2)
