SAS Macro for Outlier Capping / Flooring. ERROR

x3d1m4 · Posted 01-18-2021 12:28 PM

I try to use this macro for counting outlier values in my variables.

libname projekt "c:\";
libname projekt list;
data train;
set projekt.abt_sam_beh_train;
run;
data test_;
set train;
keep act_age;
run;

options nomprint mlogic symbolgen;
%macro outliers(input=,var=,output=);
%let Q1=;
%let Q3=;
%let varL=;
%let varH=;

%let n=%sysfunc(countw(&var));
%do i=1 %to &n;
%let val = %scan(&var,&i);
%let Q1=&Q1 &val._P25;
%let Q3=&Q3 &val._P75;
%let varL=&varL &val.L;
%let varH=&varH &val.H;
%end;

/* Calculate the quartiles and inter-quartile range using proc univariate */
proc means data=&input nway noprint;
var &var;
output out=temp P25= P75= /autoname;
run;

/* Extract the upper and lower limits into macro variables */
data temp;
set temp;
ID =1;
array varb(&n) &Q1;
array varc(&n) &Q3;
array lower(&n) &varL;
array upper(&n) &varH;
do i=1 do dim(varb);
lower(i)=varb(i)-3*(varc(i)-varb(i));
upper(i)=varc(i)+3*(varc(i)-varb(i));
end;
drop i _type_ _freq_;
run;

data temp1;
set &input=;
ID = 1;
run;

data &output;
merge tmp1 temp;
by ID;
array var(&n) &var;
array lower(&n) &varL;
array upper(&n) &varH;
do i=1 to dim(var);
if not missing(var(i)) then do;
if var(i) < lower(i) then var(i) = lower(i);
if var(i) > upper(i) then var(i) = upper(i);
end;
end;
drop &Q1 &Q3 &varH &varL ID i;
run;
%mend;
%outliers(input=test_,var=act_age,output=what_i_want);

But I get this error all the time. Have someone's a hint for this error?

Hello @x3d1m4,

There are just a few typos in the code:

```
do i=1 do dim(varb);
```
```
set &input=;
```
```
merge tmp1 temp;
```

The code can also be simplified, e.g., you don't need to create the dummy BY variable ID=1 if you use two SET statements (instead of the MERGE statement) like this:

data &output;
if _n_=1 then set temp;
set temp1;
...

I would also avoid using a function name (var) as an array name (see the corresponding note in the log: "The array var has the same name as a SAS-supplied or user-defined function. ..."). To guard against possible name conflicts I would use the %LOCAL statement and avoid generic dataset names like temp in a macro (remembering a case where a standard macro using that name was applied to a dataset temp containing temperature measurements ...). Also the comments need a revision (univariate? macro variables?).
