Variance estimation for complex indicators of poverty and inequality using linearization techniques
Survey Research Methods, 2009 The paper presents the Eurostat experience in calculating measures of precision, including standard errors, confidence intervals and design effect coefficients - the ratio of the variance of a statistic with the actual sample design to the variance of ...

Error calculation of broadband standard current transformer based on equal-ampere-turn principle
Energy Reports, 2022 Due to the lack of corresponding devices and traceability systems for wide-band current transformer verification, the wide-band current measurement requirements of many power systems cannot be solved.

From urn models to box models: Making Neyman's (1923) insights accessible
Journal of Causal InferenceNeyman’s 1923 paper introduced the potential outcomes framework and the foundations of randomization-based inference. We discuss the influence of Neyman’s paper on four introductory to intermediate-level textbooks by Berkeley faculty members (Scheffé ...

Estimating the Ratio of Means in a Zero-Inflated Poisson Mixture Model
StatsThe problem of estimating the ratio of the means of a two-component Poisson mixture model is considered, when each component is subject to zero-inflation, i.e., excess zero counts. The resulting zero-inflated Poisson mixture (ZIPM) model can be viewed as

Adaptive 2D IGA boundary element methods
, 2015 We derive and discuss a posteriori error estimators for Galerkin and collocation IGA boundary element methods for weakly-singular integral equations of the first-kind in 2D.

Identification with Imperfect Instruments [PDF]
, 2008 Dealing with endogenous regressors is a central challenge of applied research. The standard solution is to use instrumental variables that are assumed to be uncorrelated with unobservables. We instead assume (i) the correlation between the instrument and

Linking Error Estimation in Stocking–Lord Linking
FoundationsStocking–Lord (SL) linking is a widely used linking method based on item response theory (IRT). This article examines the variability in SL linking parameter estimates within the two-parameter logistic (2PL) model.

The reduction of the standard of census route length using double lamination of sample
Аграрная наука Евро-Северо-Востока, 2018 On 2 territories, different in areas and levels of linear density populations of moose, the number of wild animals by the trails on the route was counted.

Signal Estimation with Additive Error Metrics in Compressed Sensing [PDF]
, 2013 Compressed sensing typically deals with the estimation of a system input from its noise-corrupted linear measurements, where the number of measurements is smaller than the number of input components.
