The error term in a random walk is assumed to be iid (often white-noise), but the error in a martingale doesn't have to be. If the error is AR(1) however, then the process can't be martingale, as the error in last period is known, and so the current period error is not mean zero anymore. But the error may have second order serial correlation (like an ARCH process), and still be a martingale. The error in a random walk however must be independent of the prior error (at all orders).
the four economic models are as follows: two sector models three sector model four sector model five sector model
Models are used because working with and testing a model can be safer and less expensive than using the real thing.

Decision-Making Models in Business Management Rational Model – Logical, step-by-step approach for complex decisions. Bounded Rationality Model – Selects the first good-enough option due to time or cognitive limits. Intuitive Model – Relies on experience and gut feeling for quick decisions. Incremental Model – Gradual, step-by-step adjustments over time. Garbage Can Model – Decisions emerge randomly in uncertain environments. Vroom-Yetton Model – Defines leadership’s role in decision-making, from autocratic to collaborative. Businesses use these models based on complexity, urgency, and available information.
The market clearing model is a model where prices adjust to equilibrating demand and supply meaning the quantity supply equals the quantity demanded. These models are useful for studying situations where prices are flexible.

Any simulation model that does not contain any random or probabilistic element is called a deterministic simulation model. The characteristic of this type of simulation model is that the output is determined when the set of input elements and properties in the model have been specified. For example, a deterministic simulation model can represent a complicated system of differential equations. Many simulation models however, have at least one element that is random, which gives rise to the stochastic simulation model. In most simulation models randomness is important to mimic the real scenario, for example user connections to the internet arise 'randomly' when a person pressing a key. However, for any stochastic simulation model that has random output, the output (numerical results) can only be treated as an estimate of the true output parameters of the model

That varies from model to model. There are not requirements for how long models should exercise.

There are three models of a fraction namely area model, liner model and set model.
For models there are sites such as Models (dot) com, Model Mayhem and One Model Place.
Two examples of graphical models are Bayesian networks, which represent probabilistic relationships among variables, and Markov random fields, which model dependencies between variables in spatially connected domains.

The three subatomic models are the plum pudding model, the nuclear model, and the current model known as the quantum mechanical model. These models describe the structure of the atom and the arrangement of subatomic particles within it.
