Plus, get access to over 20 breakout sessions.I have the following dataset . data have; input profit; datalines; 52 34. 60. 57. 70; run; I want to write a program that will create a new dataset, only containing the difference between the first and last observation? In this case the code would show 70 (last observation) - 52 (first observation), so the output would be 18.

Here's an example of how that would work. Some efficiency tricks: Use format dtdate9 on your datetime variable to summarize data by date. Use Range for the date variable to obtain the max time - min time. Datetime is stored as seconds, so convert to a number by dividing by 60 for minutes and another 60 for hours.data step1; set have; date=datepart(datetime); time=timepart(datetime); format date yymmdd10. time tod5.; run; Now sort by subject date and time and then take the last one for that date. proc sort data=step1 out=want; by subject date time; run; data want; set step1; by subject date time; if last.date; run;

This example creates a SAS data set and executes the PRINT procedure with FIRSTOBS=2 and OBS=12. The result is 11 observations, that is (12 - 2) + 1 = 11. The result of OBS= in this situation appears to be the observation number that SAS processes last, because the output starts with observation 2, and ends with observation 12.To ensure all ties have the same rank I used the Proc rank option ties=dense. In your example data salary 10 is tied at #1 and the answer for the OP (Rank 2) will be salary of 8 for ID 1. 1 Like.

Third, I think you are confusing the levels of BY variable where first. and last. operate. First. will tag any observation that is first within it's value of the specified BY-group. Since you have unique (my guess, I don't see the actual source data) values of baseline_doc/date, every row will tagged.
