From: A maximum curvature method for estimating epidemic onset of seasonal influenza in Japan
Epidemic (Panel a) onset and (Panel b) ending thresholds (rounded to one decimal place) established for the 47 prefectures in Japan using the MCM with n = 5 and h = 5.0. The relative ordering of epidemic onsets (ends) is depicted by the bar color: white indicates prefectures with the earliest epidemic onsets (ends), and red indicates prefectures with the latest epidemic onsets (ends). The prefectures are sorted by increasing epidemic onset (ending) thresholds
