Output Data Set 
is the name of the data set to be created. Type in a one-level or two-level SAS data set name. 
                     
Interval 
is the time interval between observations (data frequency) in the simulated data set. Type in an interval name or select one
                        from the pop-up list. 
                     
Seed 
is the seed for the random number generator used to produce the simulated time series. 
                     
N Observations 
is the number of time periods to simulate. 
                     
Starting Date 
is the starting date for the simulated observations. Type in a date in a form recognizable by a SAS data informat, for example,
                        1998:1, feb1997, or 03mar1998. 
                     
Ending Date 
is the ending date for the simulated observations. Type in a date in a form recognizable by a SAS data informat. 
                     
Series to Generate 
is the list of variable names and ARIMA processes to simulate. 
                     
Add Series 
opens the ARIMA Process Specification window to enable you to add entries to the Series to Generate list. 
                     
Delete Series 
deletes selected (highlighted) entries from the Series to Generate list. 
                     
OK 
closes the Time Series Simulation window and performs the specified simulations and creates the specified data set. 
                     
Cancel 
closes the window without creating a simulated data set. Any options you specified are lost.
