im having the hardest time calculating year over year change in store traffic and trying to keep them grouped by store, theres 28 stores.
Also, my company does not pay for any forecasting tools so they have to be made from scratch. i would love to use time series regression and linear regression but would have to build them from scratch. currently im having trouble just even getting set up. I am used to python and am stuck trying to transfer those same skills as im used to syntax and so lost with the tools.
