Abstract
Ao considerar un conxunto de datos, podemos atoparnos con observacións independentes ou con observacións que presenten algún tipo de dependencia espacial ou temporal, como é o caso das series temporais. Ao ter en conta esta dependencia, xorde naturalmente a teoría estatística da análise de series temporais, na que nos adentramos nas seguintes páxinas. O obxectivo deste traballo é a descrición e comparación dos diferentes modelos e metodoloxías de análise de series temporais. Partindo desta base, comparáronse en canto a rendemento, sinxeleza, interpretabilidade e eficiencia computacional, chegando á conclusión de que os modelos máis axeitados varían en cada caso.
When taking into consideration a set of data, one can find independent observations or observations that present some kind of spacial or temporal dependence, as we see in the case of time series. By taking this dependence into account, the statistical theory of time series analysis naturally appears, as we will be discussing it over the next pages. The objective of this piece of work is the description and comparison of the different models and methodologies about time series analysis. From this comparison made on the base of the following terms: accuracy, simpleness, interpretability and computational efficiency, I have reached the conclusion that the most appropriate models vary depending on each case.
