Estimating Nonseparable Models with Mismeasured Endogenous Variables
This supplementary material contains discussions on the optimal bandwidths selection, technical proofs, and additional asymptotic results for weighted averages of effects. All assumptions, notations, and references are as given in the main body of the paper. Appendix A: Selection of Bandwidths In this appendix we provide a useful guideline on how to use leave-one-out cross-validation (Wahba, 19...
متن کاملRegression calibration for dichotomized mismeasured predictors.
Epidemiologic research focuses on estimating exposure-disease associations. In some applications the exposure may be dichotomized, for instance when threshold levels of the exposure are of primary public health interest (e.g., consuming 5 or more fruits and vegetables per day may reduce cancer risk). Errors in exposure variables are known to yield biased regression coefficients in exposure-dise...
متن کاملRegression calibration with more surrogates than mismeasured variables.
In a recent paper (Weller EA, Milton DK, Eisen EA, Spiegelman D. Regression calibration for logistic regression with multiple surrogates for one exposure. Journal of Statistical Planning and Inference 2007; 137: 449-461), the authors discussed fitting logistic regression models when a scalar main explanatory variable is measured with error by several surrogates, that is, a situation with more s...
متن کاملInstrumental Variables Methods with Heterogeneity and Mismeasured Instruments
We study the consequences of using an error-laden proxy W for instruments Z on the interpretation of Wald, local instrumental variables (LIV), and instrumental variables (IV) estimands in ordered discrete choice structural systems with heterogeneity. A proxy W need only satisfy an exclusion restriction and that the treatment and outcome are mean independent from W given Z. Unlike Z, W need not ...
متن کاملCure Rate Model With Mismeasured Covariates Under Transformation
Cure rate models explicitly account for the survival fraction in failure time data. When the covariates are measured with errors, naively treating mismeasured covariates as error-free would cause estimation bias and thus lead to incorrect inference. Under the proportional hazards cure model, we propose a corrected score approach as well as its generalization, and implement a transformation on t...
