Hi!
I would really like to know this: If a process, like the stock-market or the 
wheatherprogoses, is following a random walk (a Markov-process?) is it the best 
to predict that the market or the wheather tomorrow (the next step) is going to 
be the same as today, and why??
Very Sincerely Mikael!!
