The Statistics Department hosts weekly colloquia on a variety of statistcal subjects, bringing in speakers from around the world.

Regularization Adjusted Local Average Treatment Estimation for Regression Discontinuity Designs The regression discontinuity design is one of the most popular and credible methods available for causal inference with observational data.   Estimation of local average treatment effects in RDDs are typically based on local linear regressions using the outcome variable, a treatment assignment variable, and a continuous running variable.…
Symbolic Data Analysis: Statistical Inference on Interval Data Regression
Recent developments for analyzing droplet-based single cell transcriptomic data Single cell transcriptome sequencing (scRNA-Seq) has become a revolutionary tool to study cellular and molecular processes. The newly developed droplet-based technologies enable efficient parallel processing of thousands of single cells with direct counting of transcript copies using Unique Molecular Identifier (UMI). Despite the rapid technology advance,…
The design of the National Forest Inventory for the Royal Government of Bhutan The Ministry of Agriculture and Forests of the Himalayan nation of Bhutan recently released its second report on the forest resources of the land. Planning for its first ever National Forest Inventory(NFI) had begun in 2009 with the aim of providing a model and comprehensive accounting of the country’s terrestrial resources. Details of the sampling design and its…
Mining Differential Correlation Given data obtained under two sampling conditions, it is often of interest to identify variables that behave differently in one condition than in the other. This talk will describe a method for differential analysis of second-order behavior called Differential Correlation Mining (DCM). DCM is a special case of differential analysis for weighted networks, and is distinct from standard analyses of first order…
D-Optimal Designs for Multinomial Logistic Models We consider optimal designs for general multinomial logistic models, which cover baseline-category, cumulative, adjacent-categories, and continuation-ratio logit models, with proportional odds, non-proportional odds, or partial proportional odds assumption. We derive the corresponding Fisher information matrices in three different forms to facilitate their calculations, determine the conditions…
