Figure A1.

The values of $\mathrm{\Phi }$ for the block-structured models at $\sigma =0.01$. The box plots represent the distribution of $\mathrm{\Phi }$ at all the partitions. The red solid line indicates $\mathrm{\Phi }$ at the MIP. The green circles indicate $\mathrm{\Phi }$ at the partitions found by Queyranne’s algorithm. (a) ${\mathrm{\Phi }}_{\mathrm{SI}}$, (b) ${\mathrm{\Phi }}_{\mathrm{G}}$.
