Detecting seasonality
Assume you want to predict whether a candidate donor will donate next month. As predictive variables, you want to include variables like mean gift, maximum gift and minimum gift last month.
Given is a pandas dataframe gifts with all the donations made in 2017. Check for seasonality in the gifts, to know whether you should take into account seasonality when constructing the basetable.
