Implied odds are very important in No Limit. As octop says, it's as much about your read of the player as it is about math.

Best example is where you play a low pocket pair preflop. If you have notes (or, even better, PT data) on a player that says they'll call an all-in bet on a raggy looking flop with an overpair, it's reasonable to call even a fairly big preflop raise for the implied odds that it gives you should you make a set.

You know you'll make a set about one in nine times, and I'd round up to one in ten to account for the (rare but painful) times both of you make a set and you lose your chips. Therefore, you can call a preflop raise that is a tenth of your opponent's stack size, knowing you figure to win the remainder of their stack if you make your set. This doesn't work so well if you yourself are short stacked, of course.
