Preprocessing: Focusing on customers who first purchased between 2012-03-01 and 2012-07-01

Hello!

In the paper "A Deep Probabilistic Model for Customer Lifetime Value Prediction" it is written that

We [...] focus o the cohort of customers who first purchased between 2012-03-01 and 2012-07-01.

But I don't think you do it in your preprocessing code. Could you please tell why you don't include that step into preprocessing?

Thank you.
