I wish you made more videos. This was so thorough!!!! Soooooo much better than my professors or a lot of other videos online. Please consider making more on anything in data analytics. We would all appreciate it!!!
Thanks for posting this! One of the best R forecasting tutorials I've seen on RUclips. Would be great to see a more complex multivariate model being built and tested.
This is an outstanding video. I'm new to R and forecasting - and you got me up and running in 37 minutes and 52 seconds! I really appreciate your clear explanations of the various options; I'm excited to check out fpp3, and confident that because of your excellent instruction I'll be able to move forward with forecasting software costs for my workplace. Many thanks!
Thanks a lot! I had a task to detect an outlier in forecasting analysis in R but literally had no prior experience in R! You just saved me. This tutorial is so beginner-friendly and easy to take notes! Can't thank you enough
You should consider putting a course together, you by far have the best communication on RUclips topped off with astounding knowledge on statistics and code.
Thank you for making this video! This was a super helpful exercise and I'm sure people would love more videos on forecasting with R. Thank you for making this and all of your excellent explanation.
It was extremely helpful. Thank you so much for the video. Please make more of these videos. You explain the codes and the process comprehensively and smoothly. Great job!
Thank you so much. Detail info and I am able to follow. Better than Professors. Kindly upload more on Linear, Multi Linear, Logistic Regression. will be very helpful.
The "ets" model covered in the video chooses the "best" type of exponential smoother for the data at hand. Holt-Winters is equivalent to ETS(A,A,A). The "ets" function chose ETS(A,Ad,A) which is the same as Holt-Winters but dampens the trend a bit so the forecasts are not quite as aggressive. If you wanted to force a traditional Holt-Winters you could write: ets(Y,model="AAA",damped=FALSE)
Thank u very much Adam! You are helping me a lot with my Internship. I have only one question, My data is from 2014 JAN until 2020 JUL (monthly), do i need to make any change on " Y
Amazing video; thank you for making it. Is there a way to convert the data from the autoplot(fcst) plot into a data frame? My initial thought was to use as.data.frame(fcst), but this only shows me the forecasted numbers and not the data before then.
Hi Adam Check, Owesome video, thanks for sharing. question for you, i am working to forecast 300 cash accounts values for the month of August 2018, the dataset has data from 2016 Jan to 2018 July for each account, how do you reckon i should go about addressing such a scenario.
There are a lot of potential ways to do this. If you think each of the series is independent of one another, then you would just apply the methods from this video to each of the 300 series individually, one at a time (it would probably be worth your time to write a "loop" so that you could do all of them in rapid succession). If you think they are correlated in some way then things get more complicated. If that is the case then I think my first suggestion would be to look into "factor models" (using "principal components").
Hello! Thank you for the video, excellent job! I try to make a single graph with 3 forecast from ARIMA to compare the future trends. Is that possible on R?
Hi Jessica, yes it is! You can do something like this: autoplot(Y) + autolayer(fcst, series="Trend + Seasonal Regression", PI=FALSE) + autolayer(fcst_arima, series="Trend+Seasonal Regression (ARIMA errors)", PI=FALSE) where Y is the data, fcst is a forecast object from a linear regression, fcst_arima is a forecast object form an ARIMA forecast, and the PI=FALSE option is turning the prediction intervals off.
This is a very helpful video. Thank you! I do have a question. How do you suggest I address negative prediction intervals? I am forecasting sales and I can't imagine having negative sales in a given period.
Just saved my master thesis in economics
don't think this is master level content lol
@@winstonacousticstudio445 Well, it is in Germoney.
@@winstonacousticstudio445 what level would it be
@@emmanuelbabatunde7765 undergraduate. At least at UCLA it’s undergraduate level…
@@bylual that is udergrad
I wish you made more videos. This was so thorough!!!! Soooooo much better than my professors or a lot of other videos online. Please consider making more on anything in data analytics. We would all appreciate it!!!
sad. after 4 years only one upload! this is the best Arima + forecast I have ever seen...
Thanks for posting this! One of the best R forecasting tutorials I've seen on RUclips. Would be great to see a more complex multivariate model being built and tested.
Thank you. I may do that at some point.
@@adamcheck9108 Seriously Adam we're all waiting! Good stuff man

Beyond the obvious knowledge of both R and statistics, you hold outstanding communication skills. Great job!
We need this dude to come back
I will let him know!
One of the best videos.i like the real data and the different steps of submodes and their improvement. Excellent work!
You should consider putting a course together, you by far have the best communication on RUclips topped off with astounding knowledge on statistics and code.
the best, most comprehensive video i have seen so far!!
I'm studying econometrics with RStudio. Thanks a lot for your video! It's amazing.
Amazing, in just 30 minutes you covered the topic and code so well. Thanks a lot!
Thank you for making this video! This was a super helpful exercise and I'm sure people would love more videos on forecasting with R. Thank you for making this and all of your excellent explanation.
just saved my university project. thank you guru
It was extremely helpful. Thank you so much for the video. Please make more of these videos. You explain the codes and the process comprehensively and smoothly. Great job!
thank youu sooooo much it"s saving my masters😭🙇♀
Very useful video. You are so clear and coherent in presenting it. Thanks friend.

Thank you!
Great Job it i was very informational and easy to understand
Thank you! very clear tutorial about how to apply forecasting process.
Very Helpful!! Thanks so much
Thanks you sir for this awesome demonstration.
Very well explained, kudos !
Thank you!
Great stuff and clean coding 👌
Thank you so much. This is a very helpful lecture !
I just love this video!!!!! ❤️
Great help, Thanks a million.
you made life simple. it was very easy to follow through... wish you had done the same data in HoltWinters model too.
The "ets" model covered in the video chooses the "best" type of exponential smoother for the data at hand. Holt-Winters is equivalent to ETS(A,A,A). The "ets" function chose ETS(A,Ad,A) which is the same as Holt-Winters but dampens the trend a bit so the forecasts are not quite as aggressive. If you wanted to force a traditional Holt-Winters you could write:
ets(Y,model="AAA",damped=FALSE)
really thanks your video is the best one .
Very concise and comprehensive!!! Can't just thank you enough!! :D
Really nice and helpful... Thanks!
Awesome content. Please make more videos ❤️
Thanks, this was really helpful.
Well done. Outstanding video.
Awesome... Please do more videos like this
The data download isn't available now.
Incredible! Thank you so much.
Hello, Thanks so much for sharing this great piece. Please, how can you forecast by months?
Awesome vid! You should totally make more of them!
in 35:09 there is purple boxes will visible .. but in my program, level data in right not visible how can i get them?
Thank you, this is all very interesting!
Extremely helpful. Only problem for me is that my graph came out once and then they would not anymore. What do I to make them show. Code was correct.
Thanks again Adam. For Annual data how should frequency be set to?
Thank u very much Adam! You are helping me a lot with my Internship. I have only one question, My data is from 2014 JAN until 2020 JUL (monthly), do i need to make any change on "
Y
when you specify the start date, c(2014,2) means the 2nd month of 2014. Since your data starts in January you need to change the "2" to a "1".
You fine Sir, are what we refer to as, a god.
Great stuff. What if I have to forecast many time serieses ? Is there a way to automate their forecast en masse?
Perhaps a newb question here but does that last arima method do weighted averaging for recent historical data?
Amazing video; thank you for making it. Is there a way to convert the data from the autoplot(fcst) plot into a data frame? My initial thought was to use as.data.frame(fcst), but this only shows me the forecasted numbers and not the data before then.
Very helpful. Thank you!
Thank you very much ! it helped me a lot. Thanks again !
Good to hear - thanks!
Awesome!! We need more tutorial. Cross-correlation, and more...
