hatókörcsúszás

Hatokörcsúszás refers to a phenomenon in probability and statistics where the effective range or support of a probability distribution shifts or changes over time. This is particularly relevant in dynamic systems where the underlying parameters or environmental factors influencing the distribution are not constant. Imagine a system where the likelihood of certain outcomes is represented by a probability curve. Hatokörcsúszás occurs when this entire curve gradually moves, perhaps to the left or right, indicating that the expected values or the probabilities themselves are evolving.

This concept is often encountered in fields like signal processing, econometrics, and physics. For instance, in financial markets, the volatility of an asset might change, causing the distribution of its price movements to shift. Similarly, in control systems, the performance characteristics of a device might degrade over time, leading to a hatokörcsúszás in the distribution of its output. Identifying and understanding hatokörcsúszás is crucial for accurate modeling, prediction, and robust decision-making in these dynamic environments. It necessitates the use of adaptive techniques or time-varying models to account for the evolving nature of the data.
