Abstract
The paper discusses several nonlinear regression methods estimating contaminated radioimmunoassay data. The underlying model is an overdispersed Poisson process with four regression line parameters and one parameter related to the overdispersion of the variance. A generalized least-squares (GLS) algorithm can be used for parameter estimation of noncontaminated data. In the presence of outliers different methods are discussed such as L p -norm or nonlinear generalizations of Huber’s M-estimator. The best estimation results we get by a winsorized version of the GLS algorithm.
