[Question] Monte carlo alternative

Hi, I am simulation a daily demand for the year. However there has been a systemic change to the landscape this year, which makes this year statisically different from all the past year sales/demand data. So When I simulate the demand with past 5 yrs of sales record, it spew out inaccurate projection. What would be a good alternative model to use here instead? submitted by /u/Relevant_Brilliant_5 [link] [comments]
