Hi,

I want to create a new variable (newvar) based on conditional logic see below - i know this would be easy but I need help.

 

have:

var1  var2   var3   var4  var5  var6  

1           1      0          a       b      c            

1           1      1          b       b      c     

0           1       1         d       b      c    

1           0       0         a       b      c               

1           0       1         b       a     c               

 

want:

var1  var2   var3   var4  var5  var6  newvar

1           1      0          a       b      c      1          (if var4 or var5 =a and var1 or var2 =1 then newvar=1)

1           1      1          b       b      c      0 

0           1       1         d       b      c      0

1           0       0         a       b      c      1           

1           0       1         b       a     c       1      

             

thanks

It is easy. Catch the logical value of those joint conditions. It takes 1 when true zero otherwise.

 

data have;
input var1  var2   var3   var4 :$1.  var5 :$1.  var6 :$1.;
datalines; 
1   1   0    a   b   c 
1   1   1    b   b   c 
0   1   1    d   b   c 
1   0   0    a   b   c 
1   0   1    b   a   c 
;
run;


data want;
   set have;
   newvar = (var4 = 'a' | var5 = 'a') & (var1 = 1 | var2 = 1);
run;
