From: Country transition index based on hierarchical clustering to predict next COVID-19 waves
Visual interpretation of \(\mathscr {T}_{X}\). In this illustration, the transition index of a country X calculates the distance from its current cluster \(C_p\) to its closest one \(C_q\). For example, if this ratio increases in the next time window, the chance of moving X to \(C_q\) is greater. The dendrogram clades \(\alpha\), \(\beta\), and \(\gamma\) are used to calculate \(\mathscr {T}_{X}\).
