thanks for posting on time series... I've been looking for good tutorials for the past two months, and your videos are actually what I was looking for

THANK YOU !

Please make a machine learning crash course too! This was the exact thing I was looking over all across YouTube

Hey, quick question, not sure if you will mention it in the following videos of the series. In the previous videos you mentioned techniques to find whether data is stationary or not (by removing trend, seasonality, and even transforming the data with boxcox, log functions, etc). Now we are decomposing the "original" time series, but shouldn't we transform data first?

I mean, why should we run statistical tests for stationary data if the decomposition process doesn't use that? Is it related to assumptions? Can we only assume the time series decomposition models work if data is stationary?

And thanks for the content, mate! Really awesome and didatic

Nice. What if you have additive trend and multiplicative seasonality or vice versa, how would we decompose that? it would be tricky.

Glad to see the lighting is better than the first video but it's still too bright at the window's side.
Found you on medium, looking forward to seeing more.
