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!!!
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!
Thanks for posting this! One of the best R forecasting tutorials I've seen on CZcams. 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
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
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.
I'm studying econometrics with RStudio. Thanks a lot for your video! It's amazing.
Beyond the obvious knowledge of both R and statistics, you hold outstanding communication skills. Great job!
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!
Very good instructor! Its taken me forever to find someone good at teaching R stuff
Amazing, in just 30 minutes you covered the topic and code so well. Thanks a lot!
This is just amazing! A lot simpler than I imagined... Thank you for doing this
One of the best videos.i like the real data and the different steps of submodes and their improvement. Excellent work!
This is such an excellent walk-thru explained very well. Thanks so much for this work!
This was a very helpful guide for forecasting data. Thank you for taking the time to publish this.
Thanks, glad you found it helpful!

it was very helpfull, u saved much of my time
Incredible! Thank you so much.
Thank you so much. This is a very helpful lecture !
Thanks you sir for this awesome demonstration.
Well done. Outstanding video.
very explicit, you absolute justice to time series explanation
Great video, thank you so much!
You are a legend, thanks a million!
you are the Boss..........Awesome explanation¡¡¡¡ awesome example¡¡¡¡
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.
Thanks, this was really helpful.
you really really really helped me today thank god i found this video today
thank you so much, you saved my life
Great help, Thanks a million.
Awesome!! We need more tutorial. Cross-correlation, and more...
Awesome content. Please make more videos ❤️
Awesome... Please do more videos like this
Amazing Tutorial!!!
Thank you! This is how you teach! My lecturer would never do anything like this.
Thanks, Dean!
Great stuff and clean coding 👌
Really nice and helpful... Thanks!
really thanks your video is the best one .
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.
I just love this video!!!!! ❤️
Very helpful. Thank you!
Very well explained, kudos !
Thank you!
thank youu sooooo much it"s saving my masters😭🙇♀
Really awesome!! thank you ...
Thank you very much ! it helped me a lot. Thanks again !
Good to hear - thanks!
Just amazing. Thanks
fantastic job!
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)
Great video! Thanks
Great Job it i was very informational and easy to understand
Thank you Adam Check
Great video Adam! I'm fairly new to R and I had a question. What if I had daily data ? Would the time series (ts) line change in the code ?
For daily data you should technically set "frequency=365.25" to properly account for leap years. However some functions will require an integer value for frequency, so as long as your history isn't too long you could likely get away with "frequency=365". Some functions will not work with daily data (I don't think the exponential smoothing ones will, for example).
Thank you very much my good sir, greattt tutorial!!! is there a way to include a loop so we can use the arima model to forecast multiple timeseries? thank you again!
Sorry for slow reply. Yes there is. Suppose the matrix/dataframe holding your data is called "data" and you had "m" series that you wanted to forecast. Then you could do something like:
for(i in 1:m){
Y
this saved me, thanks
thank you very much for good presentation a bout R!
Great video. Thank you 😆
You are awesome!
very nice video,,, pls continue,,,
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".
Excellent Tutorial need more........
Thanks! What other topics or commands are you interested in?
