+The `raw` data is in the JSON format and unprocessed. The `csvs` and the `pytorch` data are processed in the following manner:
+
 - Missing values were backfilled.
 - Leap year extra day was omitted. So, each year of the daily dataset has 365 days. Similarly, each year of the weekly dataset has 52 weeks, and the monthly dataset has 12 columns. 
 - Data was pivoted. So each measurement has x columns where x is either 365, 52, or 12.
