CHAPTER 18Following is an example of putting an asterisk (*) in parentheses torequest integer values starting with 0 and increasing by 1:SERIES = y1 y2 y3 y4 (*);orSERIES = y1-y4 (*);This results in 0 as the first x-axis value and 1, 2, and 3 as subsequentvalues.Following is an example of putting the name of the slope growth factorin parentheses following each outcome in a growth model:SERIES = y1 (slope) y2 (slope) y3 (slope) y4 (slope);where slope is the name of the slope growth factor. The list function canalso be used with the SERIES option. It is specified as follows:SERIES = y1-y4 (slope);This results in the time scores for the slope growth factor being used asthe x-axis values.The SERIES option can be used to give variables and x-axis values formore than one series. The list of variables for each series is separated bythe | symbol. Following is an example for two growth processes:SERIES = y1 (0) y2 (1) y3 (2) y4 (3) | y5 (0) y6 (1) y7 (4) y8 (5);where for the first growth process, the time score for y1 is 0, the timescore for y2 is 1, the time score for y3 is 2, and the time score for y4 is 3;and for the second growth process, the time score for y5 is 0, the timescore for y6 is 1, the time score for y7 is 4, and the time score for y8 is 5.Using the list function and the name of the slope growth factor, theSERIES option is specified as:SERIES = y1-y4 (s1) | y5-y8 (s2);682
