WebThe theory of discrete probability could, in principle, begin and end with distributions only. But things get more interesting when we introduce other perspectives on understanding … In mathematics, more precisely in measure theory, a measure on the real line is called a discrete measure (in respect to the Lebesgue measure) if it is concentrated on an at most countable set. The support need not be a discrete set. Geometrically, a discrete measure (on the real line, with respect to Lebesgue measure) is a collection of point masses.

Webνpp is the pure point part (a discrete measure ). Second, absolutely continuous measures are classified by the Radon–Nikodym theorem, and discrete measures are easily understood. Hence (singular continuous measures aside), Lebesgue decomposition gives a very explicit description of measures. WebIn probability theory, a martingaleis a sequenceof random variables(i.e., a stochastic process) for which, at a particular time, the conditional expectationof the next value in the sequence is equal to the present value, regardless of all prior values. Stopped Brownian motionis an example of a martingale.
