Semi-parametric method for non-ignorable missing in longitudinal data using refreshment samples
Dr. Lan Xue (Oregon State University)
3:00 PM in SEO 636
Missing data is one of the major methodological problems in longitudinal studies. It not only reduces the sample size, but also can result in biased estimation and inference. It is crucial to correctly understand the missing mechanism and appropriately incorporate it into the estimation and inference procedures. Traditional methods, such as the complete case analysis and imputation methods, are designed to deal with missing data under unverifiable assumptions of MCAR and MAR. The purpose of this talk is to identify and estimate missing mechanism parameters under the non-ignorable missing assumption utilizing the refreshment sample. In particular, we propose a semi-parametric method to estimate the missing mechanism parameters by comparing the marginal density estimator using Hirano?s two constraints (Hirano et al. 1998) along with additional information from the refreshment sample. Asymptotic properties of semi-parametric estimators are developed. Inference based on bootstrapping is proposed and verified through simulations.

Schlesinger equations in positive characteristic
Daniel Litt (Columbia University)
4:00 PM in SEO 427
Let X be a complex manifold and E a vector bundle with flat connection on X. Then given a deformation of X, one obtains a canonical "isomonodromic" deformation of E, which, as the name suggests, preserves the monodromy of E. In the case X is the projective line minus a collection of points, these deformations are controlled by the Schlesinger equations. We define and study the analogous situation in positive characteristic.
