  2. Random walk - Wikipedia

    en.wikipedia.org/wiki/Random_walk

    An elementary example of a random walk is the random walk on the integer number line which starts at 0, and at each step moves +1 or −1 with equal probability. Other examples include the path traced by a molecule as it travels in a liquid or a gas (see Brownian motion ), the search path of a foraging animal, or the price of a fluctuating ...

  3. Continuous-time random walk - Wikipedia

    en.wikipedia.org/wiki/Continuous-time_random_walk

    In mathematics, a continuous-time random walk (CTRW) is a generalization of a random walk where the wandering particle waits for a random time between jumps. It is a stochastic jump process with arbitrary distributions of jump lengths and waiting times. [1] [2] [3] More generally it can be seen to be a special case of a Markov renewal process.

  4. Step detection - Wikipedia

    en.wikipedia.org/wiki/Step_detection

    Many algorithms explicitly fit 0-degree splines to the noisy signal in order to detect steps (including stepwise jump placement methods [2] [8]), but there are other popular algorithms that can also be seen to be spline fitting methods after some transformation, for example total variation denoising.

  5. Jump process - Wikipedia

    en.wikipedia.org/wiki/Jump_process

    A jump process is a type of stochastic process that has discrete movements, called jumps, with random arrival times, rather than continuous movement, ...

  6. Vieta jumping - Wikipedia

    en.wikipedia.org/wiki/Vieta_jumping

    In number theory, Vieta jumping, also known as root flipping, is a proof technique. It is most often used for problems in which a relation between two integers is given, along with a statement to prove about its solutions. In particular, it can be used to produce new solutions of a quadratic Diophantine equation from known ones.

    The bottom line: Like everything, coffee is best enjoyed in moderation. Overdoing it can give you the jitters, or even cause more serious health problems, but enjoying one or two cups a day—so ...

  8. Itô's lemma - Wikipedia

    en.wikipedia.org/wiki/Itô's_lemma

    Let h be the jump intensity. The Poisson process model for jumps is that the probability of one jump in the interval [t, t + Δt] is hΔt plus higher order terms. h could be a constant, a deterministic function of time, or a stochastic process. The survival probability p s (t) is the probability that no jump has occurred in the interval [0, t ...
