The phrase "a stochastic component" is correct and usable in written English.
It can be used in contexts related to statistics, probability, or any field that involves randomness or uncertainty in models or systems.
Example: "The model includes a stochastic component to account for the inherent variability in the data."
Alternatives: "a random element" or "a probabilistic factor".
The LIF neurons have a stochastic component.
In the augmented smoother, the unknown, time dependent coefficients are included in the state vector and have a stochastic component.
The approach matches the race/ethnicity distribution of the target user population and incorporates a stochastic component so that all relevant variance is retained.
By simulating the helicoidal and disordered flow of the giant cells through a stochastic component in the α coefficient, we reproduce not only the periodic behavior of the solar cycle, but also sporadic events such as the Maunder minimum.
It also contains a stochastic component modeling noise in the system (e.g., synaptic transmission, see Section 3.5).
In this view, transition rules can include a stochastic component and deterministic rules (Santé et al. 2010).
The vibration signal is assumed to be composed of a deterministic part representing large scale features, a stochastic part and noise components.
Evolution has a large stochastic component as a result of forces such as random mutation and genetic drift, and no predictive schemes will ever reach 100% accuracy.
This suggests that the evolution of assortative mating in this system has a strong stochastic component, probably as a result of which particular genes were present at the time the experiment started.
Hence, utility can be decomposed into a deterministic systematic and an unobservable stochastic component [8].
This is no surprise, as the common drums in pop/rock drum kit contain a notable stochastic component and relatively little tonal energy.
