Seasonality configuration in TS Forecast Factory tool

Highlighted
Atom

Hi all,

 

I was able to create forecast for multiple categories at one time in my alteryx model.

But unlike, single category TS forecast in Arima method, i was not able to select D=1 in 'TS Forecast Factory tool' to include seasonality in the model.

Below is the snapshot. Any help is highly appreciated.

 

Can someone shed some light?

Hello @brad567,

 

The reason this configuration option is not present in the TS Model Factory tool is due to the fact that each group would most likely require a different model, so it wouldn't be ideal to make a specification like this for every group. Also, the underlying algorithm does check whether or not a differenced variable would be ideal. However, if you are certain that differencing your variable would make it stationary (for every group), you could try manually creating  the differenced variable using a multi-row formula tool.

 

Let me know if you have any additional questions.

Hello HossC,

 

Can you provide an example of how to use multi-row to create differenced variable? Or any pictorial representation of what the data would look like would help a lot.

 

Thanks,

Judy
