Hello, can I use the "Playground" page to make a forecast with Exogenous Variables? If yes, what is the format of the .CSV that I need to upload?I think the answer to this is that they can't use the playground for this right now? @Nikhil Gupta

10/08/2024, 3:23 PMI don't think that should be an issue. The csv should contain ds, y and the exogenous variables, them TimeGPT should be able to handle it.
I have not tried it yet, but let me check and I will get back to you.

10/08/2024, 3:36 PMIt seems to be working but I am not sure how it is getting the future exogenous variable values.
@azul (she/her) (nixtla) - What happens when the data has exogenous variables and the user does not provide the X_df argument? Does it consider the future exogenous variables to be 0 or does it forecast them first before forecasting y?
Nikhil Gupta
10/08/2024, 3:36 PM@Tracy Teal - I think we need to make some enhancements to this playground to completely support exogenous variables.
Nikhil Gupta
10/08/2024, 3:40 PM@azul (she/her) (nixtla) - never mind. I see various options detailed here: https://docs.nixtla.io/docs/tutorials-exogenous_variables
Nikhil Gupta
10/08/2024, 3:47 PM@Tracy Teal - to addresss the user's questions, currently, only option 3b is supported right now.

10/08/2024, 4:03 PMThanks, so they can use historical exogenous variables, and to do that their csv should contain ds, y and the exogenous variables, them TimeGPT will be able to handle it?

10/08/2024, 5:48 PMYes, exactly. The example in the tutorial has the data format - here.
