MARK Subcommand<br />

TSPLOT 1579<br />

MARK indicates the onset of an intervention variable.<br />

• The onset date is indicated by a vertical reference line.<br />

• The specification on MARK can be either a variable name or an onset date if the DATE_<br />

variable exists.<br />

• If a variable is named, the plot indicates where the values of that variable change.<br />

• A date specification follows the same format as the DATE command; that is, a keyword<br />

followed by a value. For example, the specification for June 1955 is Y 1955 M 6 (or Y 55<br />

M 6 if only the last 2 digits of the year are used on DATE).<br />

Figure 6 shows a plot with the year 1945 marked as the onset date.<br />

SPLIT Subcommand<br />

SPLIT specifies how to plot data that have been divided into subgroups by a SPLIT FILE<br />

command. The default is UNIFORM.
