first.by variable value is=1 for the first observation in a dataset and rest of all the by group will be =0 except last.by variable. that will be one. You can observe it by writing example. if first.sex and last.x then flag=1; Thanks. Solved: Hi all, For instance a dataset is sorted by variable X.Initial missing values and First/Last (Jesse Coull's approach) instructs SAS to create all N records for each account, which then are filled with the existing data or remain blank This approach has additional advantages if one of the variables in the dataset is a time variable

Use FIRST. and LAST. variables to find count the size of groups. The first example uses data from the Sashelp.Heart data set, which contains data for 5,209 …i want to do following step. 1. see the last day in the different optionid group. if the OTM > 0.1 then output dataA. else output dataB. 2. in dataA and dataB, the hold =absolute value of the delta. 3. , the AAA is the hold -lag (hold) at the first day in the optionid group. in dataA, the AAA is AAA+strike_price. in dataB, the AAA is remained.

Example 1: Remove Duplicates from All Columns. We can use the following code to remove rows that have duplicate values across all columns of the dataset: /*create dataset with no duplicate rows*/. proc sort data=original_data out=no_dups_data nodupkey; by _all_; run; /*view dataset with no duplicate rows*/. proc print data=no_dups_data;Re: Finding the first and last values. This is another example where bad data structure causes one to write unnecessarily complicated code. First, transpose your data to a long layout: ; proc transpose data=have out=long (where=(col1 ne "")); by name; var source:; run; Now the exercise becomes very simple:SAS matches the first value in the list with the first variable in the list of elements, the second value with the second variable, and so on. Element values are enclosed in quotation marks. To specify one or more initial values directly, use the following format: (initial-value(s) ... SAS uses the last value.) You can also use RETAIN to assign ...I would use the following to extract the first day of current year: (to , putn() is abundant here): %let date_range_min = %sysfunc(intnx(year,"&sysdate9"d,0, b), date9.); Doing so, you only need to call a SAS function once, and you get to use an existing macro variable that has the system initiating date (be aware of that though). or something I would cal it cheating:

The EQUALS option, which is the default, must be in effect to ensure that the first observation for each BY group is the one that is retained by the NODUPKEY option. If the NOEQUALS option has been specified, then one observation for each BY group will still be retained by the ...

At the very first observation of each group (identified by the internal variable first.date, which takes the value 1 in this case), seq_id is set to 1. For all the next observations of the same date, the condition 'if first.date' is false so SAS applies the 'else' statement, which results in the accumulation of seq_id's previous value + 1 -> so ...

The variable, which is initialized to 0, is set to 1 when the MERGE statement processes the last observation. If the input data sets have different numbers of observations, the END= variable is set to 1 when MERGE processes the last observation from all data sets. Tip: The END= variable is not added to any SAS data set that is being created.set Analysis; if lag (visitdate)- visitdate = 90 then laginjury = 'new'; else laginjury = 'Follow-up'; run; proc print; run; I want to. 1. subset my injuries : (an injury is new if there were no previous visits with an injury within 90 days..otherwise it's a follow up) 2. Be able to mark each injury as being "new" or "follow up".In the DATA step, SAS identifies the beginning and end of each BY group by creating two temporary variables for each BY variable: FIRST. variable and LAST. variable. These temporary variables are available for DATA step programming but are not added to the output data set.1:36. The US services sector unexpectedly contracted in April for the first time since 2022 as a gauge of business activity slumped to a four-year low and a measure of input costs rose. The ...You can make use of the first. variable in the following way using enumeration within groups. As you would like to retain the 2 most recent records for each name, proceed by sorting them as follows: BY name DESCENDING date; SET mydata; count + 1; BY name DESCENDING date; IF FIRST.name THEN count=1; IF count<=2 THEN OUTPUT;Use FIRST. and LAST. variables to find count the size of groups. The first example uses data from the Sashelp.Heart data set, which contains data for 5,209 …2. To have SAS create FIRST. and LAST. automatic variables you need to use a BY statement. If you want the new variable to be coded 1/0 then no need for the IF statement, just assign the automatic variable to a new permanent variable. To make one variable that is 1 for the first and the last then just use an OR. set have; by logflag ; timeflag ...create table first_last(drop=row) as. select * from numbered . having row EQ min(row) union all. select * from numbered . having row EQ max(row) ; drop table numbered ; quit; Note that this will generate two rows if the given data set has one row (test that by un-commenting the OBS= option).

Re: First dot and last dot conversion into proc sql. There is no such thing. SQL does not guarantee the order in which it selects observation, so the "last" observation is unreliable. It could change from run to run. There is an unsupported, unguaranteed "monotonic" feature of SQL if you want to go that route.

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.

On the one hand it sounds like you want to GENERATE data based on some macro variable. If that is the case write a date step. You should be able to write the data step using data step DO looping and just set the bounds of the loops using the macro variables. data want; do c= 1 to &num_clusters;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;As was shown, MONOTONIC () is unreliable when used in conjunction with a HAVING clause.

Find duplicates save resources, ie, money, that can be used for other tasks. Using the FIRST. And LAST. expressions is a quick and easy way to find duplicated data. Using SAS expressions can save a lot of coding time. Author Clarence Wm.

However, the content of the columns can change. So, the first column with a non-missing value might change too. In this case, the SAS functions COALESCE and COALESCEC are very useful. This article explains the syntax of both functions and shows some ...If you don't have a WHERE statement in your DATA step already, that would be the simple solution. Change this: if vistdat le &cutdate; to this: where vistdat le &cutdate; The WHERE statement subsets differently than IF. When using IF, the DATA step reads in observations then deletes some of them.
