Exercise

Performing aggregation

After completing minor consulting jobs for a library and an ebook seller, you've finally received your first big market basket analysis project: advising an online novelty gifts retailer on cross-promotions. Since the retailer has never previously hired a data scientist, it would like you to start the project by exploring its transaction data. It has asked you to perform aggregation for all signs in the dataset and also compute the support for this category. Note that pandas has been imported for you as pd. Additionally, the data has been imported in one-hot encoded format as onehot.
