Thank you so much for the tutorial, I am currently developing a forecasting model using ARIMA but I don´t know if it should remove the atypical data of the model or just start from a Dickey Fuller Test to check the trend. Thank you.
My pleasure. Mateo, regarding your issue, it is highly recommended to consult your lecture/tutor since different people might have different expectations. For me, I would run for two set of results, one with the atypical data, one without. The reason is, some lecturers want the students to analyze how those abnormal data will affect the result. If the results show a significant difference which means that the abnormal data (or unforeseen circumstances) contribute a significant impact to the result, then justification needed since it might be a limitation of the model. On the other hand, some lecturers might only want the students to perform data cleansing, that's remove those abnormal data. Thanks for watching and have a nice day.

Best tutorial, but very short. How can I communicate you for better clarification?
