stochastic model [2 records]

Record 1 2004-10-26

English

Subject field(s)
  • Operations Research and Management
  • Statistics
  • Artificial Intelligence
DEF

A model using random variables.

CONT

Unlike stochastic models, which only reproduce some quantitative aspects of the external behavior under consideration, process models actually simulate the processes that give rise to this behavior.

OBS

Contrast with process model.

French

Domaine(s)
  • Recherche et gestion opérationnelles
  • Statistique

DEF

Modèle dans lequel interviennent [...] une ou plusieurs variables aléatoires.

DEF

Un modèle qui intègre les éventualités de réalisations d'événements probables ou qui attache à certains éléments des probabilités. Un modèle stochastique permet de définir une solution optimale en avenir incertain.

Record 2 2004-07-30

English

Subject field(s)
  • Meteorological Forecasting, Data Measurement and Analysis
  • Modelling (Mathematics)
DEF

A model using statistical concepts, such as probability distribution and randomness.

OBS

In many cases, stochastic models are used to simulate deterministic systems that include smaller-scale phenomena that cannot be accurately observed or modeled. As such, these small-scale phenomena are effectively unpredictable. A good stochastic model manages to represent the average effect of unresolved phenomena on larger-scale phenomena in terms of a random forcing.

French

Domaine(s)
  • Prévisions météorologiques et mesure et analyse des données
  • Modélisation (Mathématique)
DEF

Modèle fondé sur des concepts statistiques tels que le hasard et les distributions de fréquences.

Spanish

Campo(s) temático(s)
  • Previsiones meteorológicas, medición y análisis de datos
  • Modelización (Matemáticas)
DEF

Modelo que utiliza conceptos estadísticos, como la distribución de probabilidades y la aleatoriedad.
