Classical Sufficiency in Quantum Statistical Experiments
Samriddha Lahiry
A quantum measurement transforms a quantum statistical experiment into a classical one, but different measurements generally yield experiments with different statistical informatio…
Maximum entropy based testing in network models: ERGMs and constrained optimization
Subhro Ghosh, Rathindra Nath Karmakar, Samriddha Lahiry
Stochastic network models play a central role across a wide range of scientific disciplines, and questions of statistical inference arise naturally in this context. In this paper w…
Universality in block dependent linear models with applications to nonparametric regression
Samriddha Lahiry, Pragya Sur
Over the past decade, characterizing the exact asymptotic risk of regularized estimators in high-dimensional regression has emerged as a popular line of work. This literature consi…
Minimax estimation of low-rank quantum states and their linear functionals
Samriddha Lahiry, Michael Nussbaum
In classical statistics, a well known paradigm consists in establishing asymptotic equivalence between an experiment of i.i.d. observations and a Gaussian shift experiment, with th…
