Day 1

Testing your Citibike models

Now you're going to test the model you developed yesterday using trips from 2014 with data from 2015.

1. Write a new file called test_citibike_predictions.Rmd that loads in the new trips_per_day_2015.csv and weather_2015.csv files along with your saved model (from yesterday's .Rdata file), and predicts the number of trips for each day. If you used any other data for your model, make sure to include code that downloads and incorporates that data as well.
2. Compute the RMSE between the actual and predicted trips for 2015 and compare the results to what you found with cross-validation on the 2014 data.
