  • day_of_week: last contact day of the week (categorical: mon, tue, wed, thu, fri)

  • duration: last contact duration, in seconds (numeric). Important note: this attribute highly affects the output target (e.g., if duration=0 then purchased=no). Yet, the duration is not known before a call is performed. Also, after the end of the call purchased is obviously known. Thus, this input should only be included for benchmark purposes and should be discarded if the intention is to have a realistic predictive model.
