+# Shanghai License Plate Applicants
+
+Source:
+[Kaggle](https://www.kaggle.com/bogof666/shanghai-car-license-plate-auction-price).
+Data licensed under [CC0: Public
+Domain](https://creativecommons.org/publicdomain/zero/1.0/), so we can
+redistribute it as part of this repository.
+
+There seems to be a clear sudden growth in the number of applicants.
+
+Note: according to [this discussion on
+Kaggle](https://www.kaggle.com/bogof666/shanghai-car-license-plate-auction-price/discussion/73140),
+the record for 2008-02 is missing because the license plates for January and
+Feburary were auctioned off simultaneously in January. As this represents an
+uneven measurement and a missing value, we choose to split the observation for
+January and February 2008 in two, dividing the amount equally between the
+months. An alternative would be to introduce a missing value in 2008-02, but
+since many of the algorithms we wish to evaluate are not able to handle
+missing values (and any imputation method would be incorrect), we believe this
+is a reasonable way to deal with this issue.
+
+To obtain the ``shanghai_license.json`` file from the
+``Shanghai_license_plate_price_-_Sheet3.csv`` file, simply run:
+
+```
+$ python convert.py Shanghai_license_plate_price_-_Sheet3.csv shanghai_license.json
+```
