The rule says:
Your leaderboard submitted model may use additional variables from the raw Informa historical trials data from which we produced the core data matrix. But you will have to wrangle those variables to the test data also.
Can we have an example script demonstrating how to “wrange an additional variable into the test data”? I think one of the innovations we would like to see from this competition is in creating new variables, an example would be much appreciated. Thanks
