The quantification of the effects of exposure to an environmental mixture\n poses several statistica l challenges. It is often the case that exposure to multiple pollutants in teract with each\n other to affect an outcome.\n\n\n Further\, the exposure -response relationship between an outcome and some exposures\, such as som e metals\, can exhibit complex\, nonlinear forms\, since some exposures ca n be beneficial and detrimental at different ranges of exposure. To estima te the health effects of complex mixtures we propose\n sparse tensor regres sion\, which uses tensor products of marginal basis functions to approxima te complex functions. We induce sparsity using multivariate spike and slab priors on the number of exposures that make up the tensor factorization. We allow the number of components required to estimate the health effects of multiple\n pollutants to be unknown and estimate it from the data. The p roposed approach is interpretable\, as we can use the posterior probabilit ies of inclusion to identify pollutants that interact with each other.\n\n SEE THE PDF FOR MORE INFORMATION\n DTSTART:20171206T190000Z DTEND:20171206T200000Z SUMMARY:SPECIAL SEMINAR: Bayesian Variable Selection for Multi-Dimensional Semiparametric Regression Models URL:/epi-biostat-occh/channels/event/special-seminar-b ayesian-variable-selection-multi-dimensional-semiparametric-regression-mod els-283034 END:VEVENT END:VCALENDAR
