Aurore Delaigle Department of Mathematics and Statistics The University of Melbourne Location: Carslaw 173 Time: 2pm Friday, October 28, 2011 Nonparametric Regression from Group Testing Data Abstract: To reduce cost and increase speed of large screening studies, data are often pooled in groups. In these cases, instead of carrying out a test (say a blood test) on all individuals in the study to see if they if they are infected or not, one only tests the pooled blood of all individuals in each group. We consider this problem when a covariate is also observed, and one is interested in estimating the conditional probability of contamination. We show how to estimate this conditional probability using a simple nonparametric estimator. We illustrate the procedure on data from the NHANES study.
