    I would like to correct a few typos in the video. The updated lecture pdf has been corrected.
    At 13:26 in the video and slide 8, the formula for detrending should have minus in "-beta*t"
    At 18:56 in the video and slide 11 next to last line should be "gamma*

    Thank you! This is the ARIMA video I have been looking for; it made a good companion to my text (Box/Jenkins/Reinsel). I needed some good theoretical background, but also a practical explanation; your video series gives me just this. Very well done.

    The best video on the topic, very exhaustively though a bit too fast for someone new to the topic. I would still recommend to watch this video and know exaclty the topics you are wanting to learn and then explore more reading materials and watch this video again. Sounds long, but trust me that would be a shortcut for the given topic.

    Years later lol But this helps so much for my Time Series course to understand what all parts of the model mean and what it means in real life! Explained perfectly! Thanks!

    @fzhcary 6 ปีที่แล้ว

    I have seen about 10 videos about time series videos, this is the best. The length isn't too long and the explanation is clear and to the point. Not too much formulas. It would be better for the author to re-record the video with the correction.
