Hi, I am trying out the fable package by using this dataset but seems do not work.
I was trying to use : fable::ARIMA() model for 5*6 =30 series
I think the reason could be the dataset does not fit the requirements of the model.
so I want to ask, what are the requirements of the dataset then I can prepare my dataset towards the requirements.
Try to attach the dataset sample for the info but cannot upload in excel for csv formate.and i am not able also upload the pdf version of this dataset due to I am a new user.... ???
so only able to upload the screen shot
and also have specific questions as follow:
Regarding the dataset: my try out based on the video I watched here https://www.youtube.com/watch?v=6v3_AsbhqrE
Do we have number of ‘series’ limitation? If I have about 300 or 400 serise?
For each series do we have time continues requirements? E.g. say having one series called ‘cafe’ I try to have 0ne year transection data for sales, but for 356 days, I only have 278 days have sales the other days either missing or sales is zero. So in the datafram, should I put back all the 365 days for this ‘cafe’ series? Or I can just leave it be?
For different series, have different sales date: e.g. for ‘cafe’ I have 01-01, 01-02, and 01-05… but for ‘Butter’ I have 01-01, 02-01, 02-03….so the date is different and the butter I only have 159 days data
Dose that matter?
How many category columns , could we add? E.g. in the example you use 2 column, for each ‘state’ and ‘industry’ you have one series, could I add more dimension, e.g have one ‘category’ café in the city, café for lunch, …(sub industry category) and have one ‘city name’ as sub ‘state’ dimension, and now we need to use four columns, for each ‘state’ each ‘city’ , each ‘industry’ and each ’category’ have one series. Can the package dealing with 4 dimensions or even more say 6 dimensions? Or I had to prepare the data, make those 4 or 6 dimensions to only 2 columns?
Hope to get some guidance
