Missing PLK files

To avoid the Preprocessing step, could you please provide the 3 PLK files used in this notebook?

The PLK files can fail if you use different python version than the one I used. I'll try to incorporate the preprocessing to the main notebook in the future.

Or ... These files aren't that large - perhaps there's no need use the pickle format for i/o. Using .csv will mean that you don't have to clutter the main notebook with the incidental preprocessing steps?
