The Opportunity Atlas: Mapping the Childhood Roots of Social Mobility

December 3, 2018 @ 4:00 pm - 5:00 pm

Raj Chetty (Harvard University)

32-155

Abstract: We construct a publicly available atlas of children’s outcomes in adulthood by Census tract using anonymized longitudinal data covering nearly the entire U.S. population. For each tract, we estimate children’s earnings distributions, incarceration rates, and other outcomes in adulthood by parental income, race, and gender. These estimates allow us to trace the roots of outcomes such as poverty and incarceration back to the neighborhoods in which children grew up. We find that children’s outcomes vary sharply across nearby areas: for children of parents at…

Bias Reduction and Asymptotic Efficiency in Estimation of Smooth Functionals of High-Dimensional Covariance

November 30, 2018 @ 11:00 am - 12:00 pm

Vladimir Koltchinskii (Georgia Institute of Technology)

E18-304

Abstract: We discuss a recent approach to bias reduction in a problem of estimation of smooth functionals of high-dimensional parameters of statistical models. In particular, this approach has been developed in the case of estimation of functionals of covariance operator Σ : Rd → Rd of the form f(Σ), B based on n i.i.d. observations X1, . . . , Xn sampled from the normal distribution with mean zero and covariance Σ, f : R → R being a sufficiently…

Censored: Distraction and Diversion Inside China’s Great Firewall

November 27, 2018 @ 4:00 pm - 5:00 pm

Margaret Roberts (UC San Diego)

32-141

Abstract: As authoritarian governments around the world develop sophisticated technologies for controlling information, many observers have predicted that these controls would be ineffective because they are easily thwarted and evaded by savvy Internet users. In Censored, Margaret Roberts demonstrates that even censorship that is easy to circumvent can still be enormously effective. Taking advantage of digital data harvested from the Chinese Internet and leaks from China's Propaganda Department, this book sheds light on how and when censorship influences the Chinese…

Title Talk: Modeling Electricity Markets with Complementarity: Why It's Important (and Fun) Speaker: Benjamin Hobbs Affiliation: Johns Hopkins University Abstract: Electric power: done wrong, it drags the economy and environment down; done right, it could help to create a more efficient, brighter, and cleaner future. Better policy, planning, and operations models--both simple analytical, and complex computational ones--are essential if we're going to do it right. Better modeling is also fun, as the math of electricity models is inherently interesting and revealing…

Model-X knockoffs for controlled variable selection in high dimensional nonlinear regression

November 16, 2018 @ 11:00 am - 12:00 pm

Lucas Janson (Harvard University )

E18-304

Abstract: Many contemporary large-scale applications, from genomics to advertising, involve linking a response of interest to a large set of potential explanatory variables in a nonlinear fashion, such as when the response is binary. Although this modeling problem has been extensively studied, it remains unclear how to effectively select important variables while controlling the fraction of false discoveries, even in high-dimensional logistic regression, not to mention general high-dimensional nonlinear models. To address such a practical problem, we propose a new…
