SISEED= simulated data seed = 0 (clock) |
Data simulated with SIFILE= . See simulated data file. Simulated data files are constructed using a random number generator for selecting the responses. The random generator number uses a seed value to initiate its pseudo-random sequence of numbers. The seed value can either be set by the user, or be the current value of the system clock.
SISEED = 0 or 1 means use the system clock to seed the random number generator.
SISEED = 2 or above (integer) means use this value to seed the random number generator.
If more than one simulated data file is produced with SINUMBER= then
if SISEED = 0 or 1, the new current setting of the system clock is used for each simulated file
if SISEED > 1, the user-specified seed is advanced by 1 for each simulated file
Example: You want to simulate the same data set several times, so you choose the seed:
SISEED = 237 ; 237 is any number.
