30 de jun. de 2024 · In probability theory and related fields, a stochastic ( / stəˈkæstɪk /) or random process is a mathematical object usually defined as a sequence of random variables in a probability space, where the index of the sequence often has the interpretation of time.
Hace 5 días · Stochastic process, in probability theory, a process involving the operation of chance. For example, in radioactive decay every atom is subject to a fixed probability of breaking down in any given time interval. More generally, a stochastic process refers to a family of random variables indexed.
13 de jun. de 2024 · A stochastic process is called Markovian (after the Russian mathematician Andrey Andreyevich Markov) if at any time t the conditional probability of an arbitrary future event given the entire past of the process—i.e., given X ( s) for all s ≤ t —equals the conditional probability of that future event given only X ( t ).

13 de jun. de 2024 · Stochastic processes. A stochastic process is a family of random variables X(t) indexed by a parameter t, which usually takes values in the discrete set Τ = {0, 1, 2,…} or the continuous set Τ = [0, +∞). In many cases t represents time, and X(t) is a random variable observed at time t. Examples are the Poisson process, the Brownian motion ...
24 de jun. de 2024 · In the theory of stochastic processes, the Karhunen–Loève theorem (named after Kari Karhunen and Michel Loève), also known as the Kosambi–Karhunen–Loève theorem (after Damodar Dharmananda Kosambi) states that a stochastic process can be represented as an infinite linear combination of orthogonal functions, analogous to a Fourier series ...
