Stochastic

In technical analysis, a way to calculate momentum in which one only considers price movements and not trading volume. Most calculations of momentum consider both factors. See also: Stochastic oscillator.

The effect of uncertainties due to the finite truncation of the model can be estimated by running ensembles of integrations, whose members represent independent realizations of a stochastic process that describes these truncation uncertainties.
The model uncertainty described above can be approximated using an additive stochastic noise with an amplitude equivalent to the quantified uncertainty in the solutions.
The proposed stochastic devices can act as "natural annealer," helping the algorithms move out of local minimas.
In Section 3, a class of Kalman-type locally optimal filter is designed for discrete-time systems with stochastic nonlinearity functions, finite-step correlated noises, and missing measurements.
Consider the following discrete-time stochastic systems with multiplicative noises and stochastic nonlinearity functions:
An [F.sub.t]-adapted stochastic process X = [(X(t)).sub.t[greater than or equal to]0] is called a solution of equation (1) if
In the static and stochastic setting, a part of the data is modelled as random variable and respective realizations are only revealed during the execution of the plan.
In the stochastic case this approach is outlined in [16].
The following is the conception of upper and lower solutions for stochastic differential equations, which are given by N.
Based on the discussion above, in this paper, we consider a nonautonomous stochastic SIS model with periodic coefficients
