New framework unifies shrinkage and thresholding estimators in normal mean problems
Researchers have developed a new framework for approximate risk minimization in normal mean estimation problems, introducing an estimator called NOMAD. This framework unifies various shrinkage and thresholding rules, in…

New empirical Bayes method improves 1-bit matrix completion
Researchers have developed a new empirical Bayes method for 1-bit matrix completion, a technique used in applications like recommendation systems. This method, inspired by the Efron-Morris estimator, shrinks singular va…

Statistician explains Stein's paradox and its implications for parameter estimation
Stein's paradox, a counterintuitive statistical concept, demonstrates that in dimensions three and higher, a better estimate of a Gaussian distribution's mean can be achieved than simply using the drawn sample. The Jame…
