2017 SEMINARS

December 18, 2017 David B. Richardson Cancer Mortality Among Workers In The International Nuclear Workers Study (INWORKS)

1. An introduction to some of the major epidemiological studies of radiation exposed populations.

December 14, 2017 Tianxi Li

Statistical Tools for Analyzing Network-Linked Data

1. To propose a new general cross-validation strategy for networks, based on repeatedly removing edge values at random and then applying matrix completion to reconstruct the full network.

2. To obtain theoretical guarantees for this method under a low rank assumption on the underlying edge probability matrix, and show that the method is computationally efficient and performs well for a wide range of network tasks, in contrast to previously developed approaches that only apply under specific models. Several real-world examples will be discussed throughout the talk, including the effect of friendship networks on adolescent marijuana usage, phrases that can be learned with the help of a collaboration network of statisticians as well as statistician communities extracted from a citation network.

 

December 6, 2017 Joseph Antonelli

Bayesian Variable Selection for Multi-Dimensional Semiparametric Regression Models

1. The exposure-response relationship between an outcome and some exposures, such as some metals, can exhibit complex, nonlinear forms, since some exposures can be beneficial and detrimental at different ranges of exposure.

2. To estimate the health effects of complex mixtures we propose sparse tensor regression, which uses tensor products of marginal basis functions to approximate complex functions.

3. To 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 pollutants to be unknown and estimate it from the data. The proposed approach is interpretable, as we can use the posterior probabilities of inclusion to identify pollutants that interact with each other. We illustrate our approach's ability to estimate complex functions using simulated data, and apply our method to a study of the association between exposure to metal mixtures and neurodevelopment.

November 22, 2017 Andriy Derkach Simplified Power Calculations for Genetic Association Studies

1. To approximate power of linear and quadratic tests to varying degree of accuracy using a smaller number of key parameters.
