Confidence sets
"... • If the random set S(X) satisfies IPθ{S(X) ∋ θ} ≥ 1 − α for all θ ∈ Θ, S is a 1 − α confidence set. • Probability meaningful only before the datum is observed: If X = x, either S(x) ∋ θ or not. • Connected confidence set for real parameter: confidence interval (CI).Background Univariate location ..."

Modulation Estimators and Confidence Sets

, 1999
"... An unknown signal plus white noise is observed at n discrete time points. Within a large convex class of linear estimators of , we choose the estimator b that minimizes estimated quadratic risk. By construction, b is nonlinear. This estimation is done after orthogonal transformation of the data to ..."

one such asymptotic minimax property with the JamesStein estimator. We describe computational algorithms for b and construct confidence sets for the unknown signal. These confidence sets are centered at b , have correct asymptotic coverage probability, and have relatively small risk as set
Nonparametric confidence set estimation
 Math. Methods Statist
, 2003
"... Abstract: The problem of adaptive estimation of regression function from noisy observations is considered in the paper. We provide an adaptive confidence set ˆ BN of level 1 − α, 0 < α < 1, for the unknown function f. Here ˆ BN is a L2ball of (random) diameter τN, centered at the wavelet adap ..."

Clustering Confidence Sets
"... We propose a method for clustering a large set of observed objects with different noise levels based on their confidence set estimates rather than their point estimates. The minimal and maximal distances between confidence sets provide confidence intervals for the true distances between objects. The ..."

Nonoptimality of Randomized Confidence Sets
, 1988
"... Randomized confidence sets are used in classical decision theory as a device to obtain optimality results. In particular, in discrete distributions, a uniformly most accurate unbiased (UMA U) confidence set is based on an auxiliary randomizer that is independent of the data. Such procedures are sho ..."

ADAPTIVE NONPARAMETRIC CONFIDENCE SETS
, 2006
"... We construct honest confidence regions for a Hilbert spacevalued parameter in various statistical models. The confidence sets can be centered at arbitrary adaptive estimators, and have diameter which adapts optimally to a given selection of models. The latter adaptation is necessarily limited in sc ..."

Confidence Sets for Network Structure
"... Latent variable models are frequently used to identify structure in dichotomous network data, in part because they give rise to a Bernoulli product likelihood that is both well understood and consistent with the notion of exchangeable random graphs. In this article we propose conservative confidence ..."
