What sport are was this discussion about, where there was any carry-over effect at all? It has been shown pretty well that there is no such thing as a 'hot hand' in basketball, for one evening or across games. Points-scored in basketball is (at least) a continuous outcome, which makes it easier to research (that is, smaller N is needed) than dichotomous outcomes. Having hits in baseball doesn't carry over, or hitting homers. Historical winning streaks in team sports seem to match the number of consecutive games that you would expect by chance, without much in the way of assumptions.... -- Rich Ulrich, [EMAIL PROTECTED] http://www.pitt.edu/~wpilib/index.html "Taxes are the price we pay for civilization."
