1. martingale

   A martingale is a sequence of random variables (often used in financial mathematics and game theory) that has the property of the expectation of the next value in the sequence, given all prior values, is equal to the current value. In other words, the best prediction for the next value in a martingale series is the current value. This is regardless of all prior historical values. Martingales are used to model phenomena that appear to be a fair game, such as a series of coin flips.

1. Martingale

   In probability theory, a martingale is a model of a fair game where knowledge of past events never helps predict future winnings. In particular, a martingale is a sequence of random variables for which, at a particular time in the realized sequence, the expectation of the next value in the sequence is equal to the present observed value even given knowledge of all prior observed values at a current time. To contrast, in a process that is not a martingale, it may still be the case that the expected value of the process at one time is equal to the expected value of the process at the next time. However, knowledge of the prior outcomes may be able to reduce the uncertainty of future outcomes. Thus, the expected value of the next outcome given knowledge of the present and all prior outcomes may be higher than the current outcome if a winning strategy is used. Martingales exclude the possibility of winning strategies based on game history, and thus they are a model of fair games.
