I am trying to estimate kappa form a 3x3 table as follows:
 
             norm           rev          fixed
norm      300           55                22
 
rev          18            122              5
 
fixed          0             0                 0
 
This is paired data, drug a vs drug b.  The 0's in the botttom row don't
allow for a calculation (division by zero).  Is there any procedure to get
around this (i.e. estimates), so that a kappa can be calculated?
