Let $n_1=n_2=n$, let $\theta$ be the worst-case anti-Monge matrix constructed above, and observe $y=\theta+\varepsilon$, where the entries of $\varepsilon$ are independent and dist…

Let $n_1=n_2=n$, and let $\theta\in\mathcal{M}^{n,n}$ be the anti-Monge matrix constructed in the preceding proof, with $V(\theta)=V_0$ and with low-rank approximation error of ord…

Let y=\theta^*(\boldsymbol{[?])+[?] be observed under the latent-permutation anti-Monge model, and let $\bar{\mathcal{M}}$ denote the unrestricted anti-Monge parameter space. The…
