Tratified Sampling News Today

A study from the University of Illinois Urbana-Champaign found that some testing methods are more powerful than others at catching contaminants in infant formula.

Sample designs are typically developed to estimate summary statistics such as means, proportions and prevalences. Analytical outputs may also be a priority but there are fewer methods and results on how to efficiently design samples for the fitting and estimation of statistical models. This paper develops a general approach for determining efficient sampling designs for probability-weighted maximum likelihood estimators and considers application to generalized linear models. We allow for non-ign...
