st: creating new variables

[Debs Majumdar <debs_stata@yahoo.com>]

Hi Statalisters,

     I would appreciate if someone can give me a simple solution to my question.


I have 500 participants and 20 items in my dataset. 
r1-r10 are items which were shown before (present in original list) and w1-w10 
are items that were not in the original list. A word is spoken at a time and the 
participant is asked to recall if the word was present in the original list 
(1=Yes and 0=No).
 
I would like to create two variables: Hits and Misses depending on endorsement 
of the participants i.e. I need to go through each participant and calculate how 
many hits (items that have been seen before that were endorsed as having been 
seen before) were obtained and how many misses (items that have not been seen 
before that were endorsed as having been seen before).
 
Thanks,

 Debs
