Carving out predictability.

This repository uses seasonal patterns as a tool in identifying areas of what can be predicted within certain ranges. It is part of a study on marketplaces. Focusing on the issue of timeliness, a framework of analysis is proposed, designed to bring to light the points of match and contrast in the typical daily and weekly schedules of supply and demand.

The proposed approach enables an at-a-glance insight into the following questions:

« Are there any significant differences between preferred schedules on the supply and demand sides? »
« If so, when do the most critical disparities occur? »
