# Window Features Computation

![window features computation.png](wcjnwqTHTIm4)

Compute the current and future CLV based on the sliding windows. Compute extra features for the lifetime statistical model prediction.

The current month is included in the forward window but excluded from the backward window.


Compute the average monthly CLV increase for training (to capture the general dynamic of each month).

We only keep months with an entire lookback window (so the first months of the dataset are not used in the modelization as they are incomplete)
