Statistical methods for outcome misclassification adjustment in causal inference and spatial classification.
… methods using interval validation data. Regression calibration (RC) and multiple imputation (MI) are utilized to correct misclassified outcomes where a gold-standard device is not available. Spatial generalized linear mixed model (SGLMM) and indicator kriging (IK) are applied to spatial …

Multivariate Analysis of Dietary Data in the Presence of Excess Zeros and Measurement Error
… food and the traditional multivariable linear regression model widely used in nutritional epidemiology. Finally, a regression calibration approach is applied to correct for the effect of excess zeros and multiple correlated person-specific preferences when several food intakes are investigated …

Nonparametric function smoothing: fiducial inference of free knot splines and ecological applications
… Classic techniques such as locally weighted regression and smoothing splines are being used in a variety of circumstances to address questions at the forefront of ecological theory. We first examine an ecological threshold problem and define a threshold as where the derivative of the …

Measurement Error in Exposure Assessment: An Error Model and its Impact on Studies on Lung Cancer and Residential Radon Exposure in Germany
… and in the most potent confounder smoking. The regression calibration method and an approximate maximum likelihood method were applied. The differentiation between classical error (from assessing radon exposure or packyears) or Berkson error (from using radon exposure instead of alpha dose, from …

Modelling non-linear exposure-disease relationships in a large individual participant meta-analysis allowing for the effects of exposure measurement error
… application of a widely used correction method, regression calibration, to fractional polynomial models. We also consider the effects of non-classical error on the observed exposure–disease relationship, and the impact on our correction methods when we erroneously assume classical measurement …

Hydrodynamics of Saltwater Intrusion in Heterogeneous Coastal Aquifers
… by applying the Random Forest method to the regression calibration required to convert image light intensity to concentration. The method saves significant preparation time by generating a calibration that is applicable to all heterogeneous configurations, negating the need to run individual …
