ARIMA not able to find a suitable model #614

Closed ps1608 closed 4 years ago

ps1608 commented 4 years ago

I have 145 weeks of data for multiple center-meal combination. Some center-meal combination may not have all weeks data. plus there are other predictors like base_price,checkout_price,featured_pages etc . I am trying to build a arima with regression model to forecast num_orders for week 146-154, in a loop for each (center-meal combination and for the combination "55-2139" where center_id=55 and meal_id=2139, I get error "No suitable ARIMA model found"

Data for 55-2139 , is attached

Code: weekorder=subset(train,train$cMID=="55-2139") xregtrain=cbind(weekorder$checkout_price,weekorder$base_price,weekorder$emailer_for_promotion,weekorder$homepage_featured)

AutoArimaRegModel=auto.arima(weekorder$num_orders,xreg=xregtrain) --> I get the error "ARIMA could not find a suitable model" data.xlsx

Please help
