Plan IQ - Prophet Algorithm - End of year Dips
I have been using prophet to do some forecasting and with my item i have a lot of end of year dips around christmas.
I know IQ has holidays functionality which i have been using.
I have also added a holiday boolean as an explanatory variable to help.
But the forecast is still not diminishing enough on these weeks.
My historical data has a lot of dips around this time so it annoying that prophet not fully picking this up.
As i think prophet treats explanatory variables and related regressors i decided to create a another one where i add in a 1 as a continuous variable and 0 or 0.5 for the weeks where i want the data to dip in future hoping IQ reduces it. But it doesn't seem to be working.
