E.g., if I was wrong and you only want the first and last records, then the following might suffice: data want; set have end=last; if _n_ eq 1 or last then output; run; Conversely, if you actually do need the minimum and maximum dates in the file, then you could use something like: data want (drop=_:); set have end=last;num_colds = sum(0,has_cold); end; keep family_id month num_colds; run; Basically the FIRST/LAST flags for the last variable in the BY statement will change the most often since it changes both with the value of that variable changes but also when any of the variables before it changes. 0 Likes.

Luckily, this forum is full of nice people who spend a lot of their free time helping other members with their SAS (and statistics) questions. It's a great place for learning SAS (which is actually a never-ending task) because you can see how problems of all levels are tackled by experts with various backgrounds.We can use the following LAST. function in SAS to assign a value of 1 to the first observation for each team in the dataset: /*sort dataset by team*/ proc sort data =my_data; by team; run; /*create new dataset that labels last row for each team*/ data last_team; set my_data; by team; last_team=last.team; run; /*view dataset*/ proc print data ...The best thing you did is accurately count the number of elements in your array.

And I want to find the first and last non-missing observation (var) for each stn so that I could know the nonmissing var for each stn is from what time to when. What I means is, in this example, I want to find for stn 1 the first is in 12/29/2000 and the last is 1/2/2001. And for stn 2, the first is 01/01/2001, and the last is 01/03/2001.Re: Keeping first.variable. The automatic variables created through dataset options (end=, nobs=, etc) or a by statement can never be kept in a dataset. You need to assign their values to "normal" variables, which will automatically appear in the output. Hi.

In the above example what I am lloking for is writing code to basically say: If your first observation for the customer is "C" and your last is also "C" then indicator = "PASS". but if your first observation of the flag is "C" and your last observation is "O" then your indicator = "FAIL".

The multiple transposed data files then are merged back.To accomplish, he sorted the data on multiple columns with case_id as the first criteria. Then he sorted the data again with proc sort nodupkey by case_id to return the top record for each case_id. If his original sorting criteria is correct, he will return the most impacting sub-action for each case_id.This is a "must have" tool if you're going to program using SAS. first.var is created by the BY statement in the DATA step. It is automatically 1 or 0. As the data step progresses through the incoming data, whenever VAR1 takes on a new value, first.var1 is 1. Otherwise, first.var1 is 0.

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.This is a format problem. What you want is the first significant digit of the number.
