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;Solved: Hi I have a requirement to check : first date of the current month & last month's first date +1 So today's date is : 2/12/2018 I want the.

Re: How to get the first day of a week. The SAS calendar function intnx () will allow you to shift a week to wherever you want to. BUT: You need a SAS date value as starting point for this. intnx ('week',<sas date value>,0,'b') would give you the Sunday the week starts, intnx ('week.2',<sas date value',0,'b') would give you the Monday.

The first method to calculate the weighted average in SAS is with PROC SQL. The code is straightforward and easy to remember. You simply write out the formula of the weighted average. That is, you take the sum of the weights multiplied by the scores, and you divide this by the sum of the weights.Dec 8, 2009 · Dr. Smith T.

The TRANWRD function does not remove trailing blanks in the target string and the replacement string. Comparisons. The TRANWRD function differs from the TRANSTRN function because TRANSTRN allows the replacement string to have a length of zero.

If you use a by statement along with a set statement in a data step then SAS creates two automatic variables, FIRST.variable and LAST.variable, where variable is the name of the by variable. FIRST.variable has a value 1 for the first observation in the by group and 0 for all other observations in the by group.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". So the result should look like this.Re: Keep only first/last observation for EACH year of EACH company.

The substring between the beginning of the string (^) and the first hyphen as well as the substring between the last hyphen and the end of the string ($) -- both are sequences of arbitrary characters except the hyphen, denoted by [^-]*-- are not part of FINAL. The replacement \1 stands for the substring matched by the pattern .* in parentheses.Then you use by-processing and the first. and last. automatic variables, and retained variables for counters and sums.

I am using a first. last. statement to keep IDs and create an observation counter to ensure that I am keeping only those with greater than 3 observations.

Hi: FIRST.byvar and LAST.byvar are automatic variables that exist for the duration of the DATA step program, but they can be used in the program. Since they are never output to the final dataset, you might consider them temporary. I prefer to think of them as automatic, like _N_ and _ERROR_, which are also available for the duration of …

The best thing you did is accurately count the number of elements in your array.

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;Then when the code executes, SAS creates temporary numeric variables first.var1, last.var1; first.var2, last.var2. These variables have 0/1 values for false/true, and indicate if the current row is the first or last row being input into a DATA or PROC step from the BY-group defined by the specified variable.

So the 2 BY statements in your code are really independent of each other.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.SAS places FIRST.variable and LAST.variable in the program data vector and they are therefore available for DATA step programming, but SAS does not add them to the SAS data set being created. It is in that sense that they are temporary. Because SAS does not write FIRST.variables and LAST.variables to output data sets, we have to do some ...Using first.variable and last.variable to get sum of 2 observations Posted 07-10-2019 06:31 PM (3922 views) SAS Version 9.4.
