Feature engineering example

[boc410]

This is a very minor issue with the wording used in the "Domain Knowledge Features" section of the Feature Engineering notebook.

I believe the sentence should indicate there is an anomaly where some memberships expire before the transactions date (instead of after). The following code appears to apply a filter to include only data where memberships expire after the transaction date.

From the notebook:
There is one slight anomaly with the transactions where some membership expire dates are after the transactions date, so we will filter those out.

#Filter anomalies
trans = trans[trans['membership_expire_date'] > trans['transaction_date']]
