In the Supplementary Material, we provide additional discussion for (i) the derivation of ${\mathcal{T}}$ in (2.1); (ii) sensitivity analysis of the global testing results in Section 2.1; (iii) the comparison of the $\ell _{0}$ segmentation approach we used for Problem (2.4) versus PELT (Killick, Fearnhead and Eckley (2012)); (iv) discussion of local $p$-values on synthetic data; and (v) modification of Problem (2.8) to handle irregularly spaced time points.
