Creating new variable but everything goes missing?

[robertrao]

Hi Sorry about that..

The code which you posted works exactly fine...

Secondly, I was trying to run it by replacing

delivery_premature = (. < labor < 37);  with what you explained.......

if (. < delivery < 37) then delivery_premature = 1;

     else delivery_premature = 2;      /*did u put this 2 here by mistake........i think it should be 0 because the format has only 1 and 0 and no 2*/

Please correct me

Yes, you are correct it should be 0 (to allow for my format definition to work), or if you prefer to be 2, then you change

proc format;

value yesno 1 = "Premature" 2 = "Not premature"

;

quit;

Either 2 or 0, whatever you prefer.

Good.

Now, do you have your data set working?

Also shouldnt the highlighted "DELIVERY " be replaced by LABOR

Secondly, I was trying to run it by replacing

delivery_premature = (. < labor < 37);  with what you explained.......

if (. < delivery < 37) then delivery_premature = 1;

     else delivery_premature = 2;      /*did u put this 2 here by mistake........i think it should be 0 because the format has only 1 and 0 and no 2*/
