Create group variable in array by interval

Cruise — Thu, 08 Feb 2018 02:40:57 GMT

Hi y'all,

Please help create a group variable risk [i] in data step to my existing set of dataset.

where:

median of data is 300

risk[1]=300/3

risk[last]=300*3

by interval of 10.

The range has to be 300/3-300*3 with median of 300.

data temp; set agerisk;
  array risk {i};
  do i=1 to dim[risk];
  ...
  end;
run;

What am i doing wrong here? I simply want two variables created to the same number of rows in a new dataset?

data c.temp;
do risk=1 to 15 by 1;
do val=100 to 1500 by 100;
end;
end;
output;
run;

Hard to tell what you are doing wrong with out knowing what the output should look like.

But if you want output for each iteration the OUTPUT has to be inside one of the loops. likely

data c.temp;
   do risk=1 to 15 by 1;
      do val=100 to 1500 by 100;
         output;
      end;
   end;
run;

1 100
2 200
3 300
4 400
5 500
6 600
7 700
8 800
9 900

That looks like you want to create a val as 100* risk. Which would be:

data want;
   do risk=1 to 15;
      val = Risk*100;
      output;
   end;
run;
