HIV RNA viral load measures are often subjected to some upper and lower detection limits depending on the quantification assays. Hence, the responses are either left or right censored. Linear/nonlinear mixed-effects models, with slight modifications to accommodate censoring, are routinely used to analyze this type of data. Usually, the inference procedures are based on normality (or elliptical ...

background: standardization of the semen analysis may improve reproducibility. we assessed variability between laboratories in semen analyses and evaluated whether a transformation using z scores and regression statistics was able to reduce this variability. materials and methods: we performed a retrospective cohort study. we calculated between-laboratory coefficients of variation (cvb) for spe...

We define a notion of determining sets for the discrete Laplacian in a domain Ω. A set D is called determining if harmonic functions are uniquely determined by providing their values on D, and if D has the same size as the boundary of Ω. It is shown that there exist determining sets that are fairly evenly distributed in Ω. A number of basic properties of determining sets are derived.

Abstract: In the present paper we consider Laplace deconvolution problem for discrete noisy data observed on an interval whose length Tn may increase with the sample size. Although this problem arises in a variety of applications, to the best of our knowledge, it has been given very little attention by the statistical community. Our objective is to fill the gap and provide statistical analysis ...
