Deconvolution-based score tests in measurement error models. (English) Zbl 0724.62070

Summary: Consider a generalized linear model with response Y and scalar predictor X. Instead of observing X, a surrogate \(W=X+Z\) is observed, where Z represents measurement error and is independent of X and Y. The efficient score test for the absence of association depends on \(m(w)=E(X| W=w)\) which is generally unknown.
Assuming that the distribution of Z is known, asymptotically efficient tests are constructed using nonparametric estimators of m(w). Rates of convergence for the estimator of m(w) are established in the course of proving efficiency of the proposed test.
