Creating new variable and formulating its value to depend on other variables

[aespinarey]

Hi all!

I am having trouble creating a new variable "disease" that would determine whether or not the subject has the disease (1) or does not (0), depending on the symptoms listed on 5 different variables. If patient has sympt1-sympt3 (heartburns, sickness, and spasm) without sympt4 and/or sympt5 (temperature and/ or tiredness), then patient has disease (1). If the conditions are any different then disease should equal 0.

CODE:

options nodate nonumber;
****1.IMPORT;
%macro P3 (a, b, c, d);
proc import out= &a
datafile= "C:\HW5\&b"
dbms=xlsx replace;
getnames=yes;
run;
proc sort data=&a;
by &c &d;
run;
Proc print data = &a;
Run;
%mend P3;

%P3 (PROJECT3_F17, Project3.xlsx, id_no, symptom_no);
***2.REORGANIZE variables: USE ARRAY STATEMENT ALONG WITH FIRST.ID and LAST.ID;
data sympt (drop=symptom_no symptom);
set PROJECT3_F17;
retain sympt1-sympt5;
length sympt1-sympt5 $15;
array symptoms (5) $15. sympt1-sympt5;
by id_no;
if first.id_no then call missing(of symptoms(*));
symptoms(symptom_no)=symptom;
if last.id_no then output;
run;
proc print data=sympt;
run;
***3.Set disease=1 if sympt1+sympt2+sympt3 and no sympt4-sympt5 WORK OFF DATA SET SYMPT;
data dis_01 (drop=answer);
set sympt;
retain disease;
array dpthdisease (1) disease;
by id_no;
if first.id_no then dpthdisease (symp1-sympt5)=answer;
If answer EQ sympt1-sympt3 and NE sympt4 OR sympt5 then disease=1;
else disease=0;
if last.id_no then output;
run;
proc print data=disease;
run;
