20080321Workshop on Statistical Methodology of Microarray DataSmall volume imaging
Prof. Hyeonbae Kang ( Inha University, South Korea )2008  03  21 (Fri.)
10:00  11:00
308, Mathematics Research Center Building (ori. New Math. Bldg.)Lecture 1. Method of Small Volume Expansions and its Applications to Medical Imaging I will explain the mathematical theory of the small volume expansions in the context of the conductivity equation, which is the simplest possible model. I then discuss how this mathematical theory can be applied to an electrical impedance tomography problem to detect small inclusions buried inside a body. Lecture 2. Mathematical Analysis for MRElastography and Applications MRElastography is a recent modality to image the internal part of body using the internal measurements of the displacement vectors. One of the advantages of the imaging method using MRE over other methods is that it can detect the stiffness parameter of the tissue, by which we can distinguish malign cancer from benign cancer. In this lecture I will explain a new method of reconstruction using MRE data. Lecture 3. New reconstruction methods for Magnetoacoustic Imaging. A new and promising technique in the medical imaging is to excite a local part of body using acoustic or ultrasonic focusing and to measure changes due to the excitation. I will explain new reconstruction methods for the Magnetoacoustic imaging and the vibration potential tomography.

20080321Statistical MethodologyPseudoPartial Likelihood for Proportional Hazards Models with BiasedSampling Data
Prof. WeiYann Tsai ( Department of Biostatistics, Columbia University, USA )2008  03  21 (Fri.)
14:30  17:00
502, Freshman Classroom BuildingWe obtain a "pseudopartial likelihood" for proportional hazards models with biasedsampling data by viewing biasedsampling data as lefttruncated data. The log pseudopartial likelihood of the biasedsampling data is the expectation of the log partial likelihood of the lefttruncated data conditioned on the observed data. In addition, asymptotic properties of the estimator which maximizes the pseudopartial likelihood are derived. Applications to lengthbiased data, biased samples with right censoring, stratified samples, and proportional hazards models with missing covariates are also discussed. 
20080321Workshop on Statistical Methodology of Microarray DataReconstruction methods for inverse problems
Prof. Gen Nakamura ( Hokkaido University, Japan )2008  03  21 (Fri.)
11:20  12:20
308, Mathematics Research Center Building (ori. New Math. Bldg.)For the recent 10 years the several reconstruction methods have been proposed for inverse scattering problems and inverse boundary value problems. For instance they are the linear sampling method, factorization method, probe method, singular sources method, noresponse test, range test and enclosure method etc. These reconstruction methods are noniterative methods which means that they are not data fitting methods such as the least square methods or the regularized version of those. They provide how to reconstruct the unknowns directly from the given measured data. The lecture will touch the basic ideas of those methods and discuss about their convergence and relations between them. 
20080321Statistical MethodologyPseudoPartial Likelihood Estimators for Cox Regression Model With Missing Covariates
Prof. WeiYann Tsai ( Department of Biostatistics, Columbia University, USA )2008  03  21 (Fri.)
14:30  17:00
502, Freshman Classroom BuildingBy embedding the missing covariate data into a lefttruncated and rightcensored survival model, a new class of weighted estimating functions is proposed for Cox regression model with missing covariates. The resulting estimators, called the pseudo partial likelihood estimators (PPLEs), are shown to be consistent and asymptotically normal. Simulation study demonstrates that PPLEs, compared with the popular inverse probability weighted estimators, have better performance when the observation probability is small, and improve efficiency of estimating the missing covariate effects. A real data example is applied to illustrate the use of PPLEs.
