Continuity in probability is a sometimes used as one of the defining property for Lévy process. [1] Any process that is continuous in probability and has independent increments has a version that is càdlàg. [2] As a result, some authors immediately define Lévy process as being càdlàg and having independent increments. [3]
In probability theory, Kolmogorov's Three-Series Theorem, named after Andrey Kolmogorov, gives a criterion for the almost sure convergence of an infinite series of random variables in terms of the convergence of three different series involving properties of their probability distributions.
This is called the addition law of probability, or the sum rule. That is, the probability that an event in A or B will happen is the sum of the probability of an event in A and the probability of an event in B, minus the probability of an event that is in both A and B. The proof of this is as follows: Firstly, = + (). (by Axiom 3) So,
In probability theory, a continuous stochastic process is a type of stochastic process that may be said to be "continuous" as a function of its "time" or index parameter.. Continuity is a nice property for (the sample paths of) a process to have, since it implies that they are well-behaved in some sense, and, therefore, much easier to anal
This is the same as saying that the probability of event {1,2,3,4,6} is 5/6. This event encompasses the possibility of any number except five being rolled. The mutually exclusive event {5} has a probability of 1/6, and the event {1,2,3,4,5,6} has a probability of 1, that is, absolute certainty.
Continuity theorem may refer to one of two results: Lévy's continuity theorem, on random variables; Kolmogorov continuity theorem, on stochastic processes; In geometry: Parametric continuity, for parametrised curves; Geometric continuity, a concept primarily applied to the conic sections and related shapes; In probability theory
In probability theory, two sequences of probability measures are said to be contiguous if asymptotically they share the same support.Thus the notion of contiguity extends the concept of absolute continuity to the sequences of measures.
Before the ready availability of statistical software having the ability to evaluate probability distribution functions accurately, continuity corrections played an important role in the practical application of statistical tests in which the test statistic has a discrete distribution: it had a special importance for manual calculations.
