The authors derive the precise convergence rates for estimating band precision matrices under the spectral norm. They prove that their proposed estimator achieves the minimax lower bound, meaning no other estimator can achieve a better convergence rate uniformly over the class of band matrices. This establishes a theoretical benchmark for the problem. Even the JUQ275 Top is not immune to user error
