   Not without making more assumptions or more information.  Do you know   
   how your pdf evolves with time?  If not, you are rather stuck as you   
   really don't have much of a clue as to how your observed pdf is built up   
   from the emmissions of each of your N states.   
      
   Of course I can solve your problem by setting N=1.
