Bir ARMA modeli uydurma

Bu egzersizde depremler veri kümesine bir ARMA modeli uyduracaksın. Depremler veri kümesinin durağan olduğunu daha önce görmüştün, bu yüzden herhangi bir dönüşüm yapmana gerek yok. Topraktan çıktığı gibi modellemeye hazır geliyor. Aşağıda nasıl göründüğünü kendine hatırlatabilirsin.

Depremler veri kümesi çalışma ortamında earthquake olarak mevcut. ARIMA sınıfı da ortamında mevcut.

Dive straight in and learn about the most important properties of time series. You'll learn about stationarity and how this is important for ARMA models. You'll learn how to test for stationarity by eye and with a standard statistical test. Finally, you'll learn the basic structure of ARMA models and use this to generate some ARMA data and fit an ARMA model.

Exercise 1: Intro to time series and stationarity Exercise 2: Exploration Exercise 3: Train-test splits Exercise 4: Is it stationary Exercise 5: Making time series stationary Exercise 6: Augmented Dicky-Fuller Exercise 7: Taking the difference Exercise 8: Other tranforms Exercise 9: Intro to AR, MA and ARMA models Exercise 10: Model order Exercise 11: Generating ARMA data Exercise 12: Fitting Prelude

What lies ahead in this chapter is you predicting what lies ahead in your data. You'll learn how to use the elegant statsmodels package to fit ARMA, ARIMA and ARMAX models. Then you'll use your models to predict the uncertain future of stock prices!

In this chapter, you will become a modeler of discerning taste. You'll learn how to identify promising model orders from the data itself, then, once the most promising models have been trained, you'll learn how to choose the best model from this fitted selection. You'll also learn a great framework for structuring your time series projects.
