We discuss robust estimates based on leverage downweighting of the coefficients in logistic regression case-control studies when the true predictor X is an unobserved continuous random variable, and instead a surrogate W is observed with nondifferential measurement error. The asymptotic theory of the estimates is derived, and consistent standard error estimates obtained. An illustrative example shows that the adverse effects of outliers upon standard methods can be somewhat ameliorated by our techniques.
