Freqüentista

Freqüentista is a term used in the context of probability and statistics to describe a method of inference based on the frequency of events. This approach assumes that the probability of an event is the limit of its relative frequency as the number of trials approaches infinity. In other words, freqüentista methods rely on the idea that the probability of an event can be estimated by observing the frequency of that event in a large number of trials.

The freqüentista perspective is one of the two main approaches to probability, the other being the Bayesian approach. While Bayesian methods incorporate prior beliefs and update them with new data, freqüentista methods focus solely on the observed data and the frequency of events. This distinction is crucial in statistical inference, as it influences the interpretation of results and the choice of statistical methods.

Freqüentista methods are widely used in various fields, including physics, engineering, and social sciences. They provide a framework for making inferences about populations based on sample data, and they are particularly useful when dealing with large datasets. However, they also have limitations, such as the need for a large number of trials to ensure accurate estimates and the assumption that the probability of an event remains constant over time.

In summary, freqüentista is a term that refers to a method of inference based on the frequency of events. It is one of the two main approaches to probability, along with the Bayesian approach, and it has wide applications in various fields. However, it also has limitations and assumptions that must be considered when using this method.
