Spectral Stats - Pre-TI10 Teams Stats Recap - Items - Item Pairs

Explain this to me

This section shows the most often occuring item pairs, as well as their stats, filtered by the third quantile in number of matches together for item pairs. Timing difference shows the difference in purchase time of the first item compared to the second one. Expectation is the expected number of purchases together. Deviation represents how often these items are picked up together on purpose (higher positive numbers are better). Percentage is the deviation's part of the total number of purchases together.
