Abstract: Human biomonitoring involves measuring the accumulation of contaminants in biological specimens (such as blood or urine) to assess individuals exposure to environmental contamination. Due to the expensive cost of a single assay, the method of… read more here.

Abstract: Finite mixture of regressions (fmr) are commonly used to model heterogeneous effects of covariates on a response variable in settings where there are unknown underlying subpopulations. fmrs, however, cannot accommodate situations where covariates' effects also… read more here.

Abstract: It is shown that the weighted residual-based estimator of Schick, Zhu, and Du (2017) is efficient in some special cases and can be made to be efficient by adding a stochastic correction term. The efficiency… read more here.
