# Business Parameters

 - Last study date: Most recent study date; the first day of the last month we will use in the modeling. Remember that since we use the first day of the month as a reference, transactions during the current months are not considered (to do so, please select the next month as the last study date).
 
 By default, the max date is the first day of the following month after the last transaction in the dataset. You can select the year and month for the last study date using a custom date.
 
 
 
 
 - Historic months to keep: Total number of historic months used in the modeling
 - Past months window: Number of the past month used as inputs for feature engineering for a given data point
 - Past months window: Forward window in a number of months
 - Low transaction threshold: Threshold for a low number of transactions per customer (in the sliding backward window).
