Abstract
We discuss semiparametric regression when only the ranks of responses are observed. The model is , where is the unobserved response, is a monotone increasing function, is a known vector of covariates, is an unknown -vector of interest, and is an error term independent of . We observe , where is the ordinal rank function. We explore a novel estimator under Gaussian assumptions. We discuss the literature, apply the method to an Alzheimer's disease biomarker, conduct simulation studies, and prove consistency and asymptotic normality.
