Simple Sensitivity Analysis for Differential Measurement Error. [PDF]
American Journal of Epidemiology, 2018 Sensitivity analysis results are given for differential measurement error of either the exposure or outcome. In the case of differential measurement error of the outcome it is shown that the true effect of the exposure on the outcome on the risk ratio ...

Heterogeneity, Measurement Error, and Misallocation: Evidence from African Agriculture
Journal of Political Economy, 2019 Standard measures of productivity display enormous dispersion across farms in Africa. Crop yields and input intensities appear to vary greatly, seemingly in conflict with a model of efficient allocation across farms.

Drifted Uncertainty Evaluation of a Compact Machine Tool Spindle Error Measurement System
MachinesThe accurate measurement of spindle errors, especially quasi-static errors, is one of the key issues for the analysis and compensation of machine tool thermal errors in machining accuracy. To quantitatively analyze the influence of the measurement system’
