modellfeltevéseket

Modellfeltevés is a Hungarian term that translates to "model assumption" or "model premise." It refers to the fundamental statements or conditions that are established or accepted as true at the beginning of a modeling process. These assumptions are crucial because they define the scope, limitations, and behavior of the model being developed. Without clear and well-defined model assumptions, a model can be ambiguous, inaccurate, or inapplicable to the real-world phenomenon it aims to represent.

In various fields, such as mathematics, physics, economics, and computer science, model assumptions are explicitly stated to provide a foundation for subsequent analysis and prediction. For instance, in physics, a common model assumption might be that an object is a point mass or that friction is negligible. In economics, assumptions about rational economic agents or perfect competition are often made. These assumptions simplify complex realities, making them amenable to mathematical treatment and theoretical development.

The validity of a model is intrinsically linked to the appropriateness of its underlying assumptions. If the assumptions do not adequately reflect the real-world situation, the model's predictions or conclusions may be misleading. Therefore, a critical part of model building and evaluation involves scrutinizing and validating these assumptions. This can involve comparing model outputs with empirical data, conducting sensitivity analyses, or revisiting the theoretical underpinnings of the model. Understanding and articulating the modellfeltevés is therefore a cornerstone of responsible and effective modeling.
