Thank you so much! I did it! Actually, I have an assignment about time series prediction which I have never touched before and this assignment is determining whether I could get this job. Now I got it after following your step, thank you so much!
Tested it today 2019/10/30 and some minor differences, for instance it plotted the time of day the page was most active, also the 'count' variable was missing, so I used 'views' and it got to basically the same results. Thanks for all these great RStudio videos.
Sir, You are amazing as always. Don't know what to say. I wish i could thank you more and more. This actually is an amazing package by facebook and it worked like a gem. you are the living God. Salute to your content, expertise, precision, dedication. My role model. I aspire to pursue my career as a data scientist in near future. Need your blessings and guidance. Do revert if you see my message, please. Thanks a lot Guru Ji.
Thank you for your efforts...please guide me regarding the forecasting of exchange rates...is it follow the same package and method or there is a need to install another package
Hello sir, Nice explanation..I have a question . Lets say we are forecasting for number of units sold in an inventory and as there will be many products is there any specific package that can be used to forecast on each product or should we use a for loop?? Thank you
Thanks a lot for a nice explanation of the usage of prophet package. I have a question. If the data is not stationary, can we still continue building time series model using prophet (without making it stationary - as we do in arima model) ?
Good stuff. Can we use this model to predict stock market index like SENXEX, NIFTY etc? One more query, if we want to add a variable like Govt. in power, ie we wd be having - Date, Senxex/Nifty closing index, Govt in power then how to go about that... thanks
i'm getting this error Error in setup_dataframe(m, history, initialize_scales = TRUE) : Unable to parse date format in column ds. Convert to date format (%Y-%m-%d or %Y-%m-%d %H:%M:%S) and check that there are no NAs. after using prophet(df) , can u suggest?
Can u pass the parameter and based on parameter selection, can we predict the value? So we will get overall next 365 days prediction or based on some attribute selection seperately
Hi Sir, Can you please help me? I have one categorical exogenous column which contains 3 fields in it. I am trying to forecast using SARIMAX with R Code. Requesting you to please do refer some links or material?
I have tried using with my data and my y values are more than 50,000 in most of the cases and the yhat doesn't cross even 9 ( log of 9 is 8k). I think I am doing something wrong here but I just don't know what.
Hi, this is the first video that demonstrates the workings of prophet, so thanks for that. Just a thought, I've been using prophet extensively for forecasting sales and more often than not it has disappointed me. I found its capabilities shine over other methods only in case when series is very ideal. Not sure if I'm missing something or it's actually a problem. Did you try prophet on any other complex series? Also, you did not split the dataset into test and train to calculate accuracy, any specific reason for that?
The wikipediatrend package currently has no server providing any page view information. Use package pageviews for recent (2016+) information. Older information hopefully available again soon.
Hello, this is a great video! I am stuck on the package install of prophet, there is no package with that name when I search. Do you know if that package is still available today (2020-04-23). thank you!
Hi Blake. Go to cran and download the package from here cran.r-project.org/web/packages/prophet/index.html then install by pointing to your download folder. I managed to install it using this method and did the whole turtorial

Hello sir, Great video, very well explained! I have a question . I have daily data. When I apply m = prophet (df), on my console doesn't appear STAN OPTIMIZATION COMMAND. Please help me in this issue. Thank you
Hi Sir, what forecasting method will best work if the data is at weekly level. like below Jan 2, 2012 Jan 9, 2012 Jan 16, 2012 Jan 23, 2012 ... Mar 17, 2014 Mar 24, 2014 Mar 31, 2014 or do i have to change first into Time series before starting with a forecasting model. Need your urgent help sir.
In the video I showed using plots how log helps to see the patterns. But if you have data where without log transformation, patterns are clearly visible, then you don't need it.
when you provide day/month/year data, the package already takes care of day of the week. The chart towards the end of the video has seasonality index plotted by day of the week.

In the forecast there are no black dots representing actual values.
