How can we dictate the seasonality factor in ARIMA Tool in Alteryx. 

 

ARIMA(p,d,q)(P,D,Q)m - factor m which determines what is a full season is missing in the tool. m=12 for 1 year in monthly data.

Hi @cnaveen02,

 

Your selection for the Target Field Frequency determines the value of m used by the model... Selecting Quarterly sets m = 4, monthly sets m = 12, etc.

Isn't that the granularity of the incoming data?

You are correct.

 

Per Forecasting: Principles and Practice m = the number of observations per year. The tool uses your selection to set the value of m.
