Dr. Wang will give invited talk at Northwestern University
Dr. Haiyan Wang will present "A classification Method for predicting type 2 diabetes mellitus using sequencing data" at Northwestern University's Statistics seminar series, on Wednesday, October 24, 2018 from 11:00 am to 12:00 pm.
Type 2 diabetes mellitus (T2DM) affects the lives of millions of people through its life-altering complications. Current methods of identifying genetic polymorphisms responsible for T2DM face the limitation of sample size and low accuracy at the population level (AUC of 0.68 or below). This research presents a method to identify subtle effects of genetic variants using whole genome sequencing data and improve prediction accuracy of T2DM at the population level. To achieve this, a new feature selection procedure and a classier were proposed. The method involves (1) first applying sparse principal component analysis (PCA) to genotype data to obtain orthogonal features; (2) using SNP-specific regularization parameters to reduce the false positive rate of feature selection; (3) verifying feature relevance through Lasso penalized logistic regression in conjunction with sparse PCA. After applying to a dataset containing 625,597 SNPs and 23 environmental variables from each of 3,326 humans, the method identified over 450 genetic variants that each have subtle effects on T2DM prediction. These variants, in conjunction with clinical characteristics, led to greatly improved prediction accuracy (AUC 0.79) for new patients at the population level. The proposed method also has the advantage of computational efficiency, which is 20 times faster than Random Forest classifier, and thus provides a promising tool for large-scale genome-wide association studies.

Undergraduate Research Awards
Audrey Chang and Graham Seacat have each been awarded an Arts & Sciences Undergraduate Research Scholarship for 2016-1017. Audrey is working with Dr. Wei-wen Hsu and Graham is working with Dr. Trevor Hefley.
The purpose of this project is to use a zero-inflated Poisson model coupled with working independence assumptions to analyze the longitudinal tornado data in the state of Kansas from 1950 to 2015. The zero-inflated models are used often to accommodate excess zero counts in data. In the Kansas tornado data, the number of counties with no tornado touch downs during a certain period of time was often observed, therefore creating many zero counts. We started this project in August 2016, with Dr. Wei-Wen Hsu of the Statistics Department as my mentor. Through the proposed model, we will identify factors (e.g., location of county, season, temperature, etc.) that can be used to predict the frequency of tornado touch-downs in the future. We expect that the model can provide a new perspective about tornado monitoring and gain new understanding to Kansas’ tornado patterns.
This first semester, we have set aside two months reading and understanding of the data and related literature about the tornadoes and zero-inflated Poisson models, respectively. We are currently finishing up the data preparation (i.e., data merging and data cleaning) using statistical software SAS and will focus on the model development and data visualization for Kansas tornado data in the following few months. Starting February 2017, we will write a scientific paper and hope to publish our findings in a scientific journal afterwards as well as present our findings at a national or international conference.
The purpose of this study is to implement statistical analysis in the field of ecology to learn more about the behavior of mule deer (Odocoileus hemionus). Animal behavior is the link between the biology of the animal and the ecosystem in which it lives. I plan to apply our movement modeling approach to a telemetry dataset, collected from GPS devices that measure location and heart rate, on mule deer from the Piceance basin in Colorado, USA. The data points typically are separated into two “behavioral states”, moving and sleeping. Unlike many telemetry data sets, the proposed dataset is ideal to test our methods because field based observations that provide visual proof of the animals’ behavior are also available.

Audrey Chang receives Undergraduate Research Award
Audrey Chang has received an award for Undergraduate Research in the College of Arts & Sciences for Fall 2016. She will be working with Dr. Wei-Wen Hsu to develop a zero-inflated Poisson model for Kansas' tornadoes.
The purpose of this project is to use a zero-inflated Poisson model coupled with working independence assumptions to analyze the longitudinal tornado data in the state of Kansas from 1950 to 2014. The zero-inflated models are used often to accommodate excess zero counts in data. In the Kansas tornado data, the number of counties with no tornado touch downs during a certain period of time was often observed, therefore creating many zero counts. Through the proposed model, we will identify factors (e.g., location of county, season, etc.) that can be used to predict the frequency of tornado touch downs in the future. We expect that the model can provide a new perspective about tornado monitoring and gain new understanding to Kansas’ tornado patterns.
The first two months will be set aside for reading and understanding of the data and related literature about the tornadoes and zero-inflated Poisson, respectively. The next three months we will conduct real data analysis using R and/or SAS as well as some data managements (i.e., data merging and data cleaning). The rest of the year will be used to write a scientific paper of the findings. We hope to publish our findings in a scientific paper afterwards.

R. Dennis Cook is named KSU Alumni Fellow
R. Dennis Cook has been named 2016 KSU Alumni Fellow for the College of Arts & Sciences. Dr. Cook is currently a full professor and director of the School of Statistics at the University of Minnesota. He earned a master's degree in statistics from K-State in 1969 and a doctorate, also in statistics from K-State, in 1970. At the University of Minnesota, he has served a ten-year term as Chair of the Department of Applied Statistics, and a three-year term as Director of the Statistical Center.
His research areas include dimension reduction, linear and nonlinear regression, experimental design, statistical diagnostics, statistical graphics and population genetics. He has authored over 200 research articles and is author or co-author of two text books – An Introduction to Regression Graphics, and Applied Regression Including Computing and Graphics – and two research monographs, Influence and Residuals in Regression, and Regression Graphics: Ideas for Studying Regressions through Graphics. View background on his research.
In a seminal 1977 publication, Dr. Cook introduced Cook’s Distance (Cook’s D), a widely used statistic that measures the relative influence of each individual case in a sample of data on the results of a regression analysis. It is used to discover whether one or more cases have such a large effect that they might distort the overall results of the regression.
Dr. Cook has served as Associate Editor of the Journal of the American Statistical Association, The Journal of Quality Technology, Biometrika, Journal of the Royal Statistical Society and Statistica Sinica. He is a four-time recipient of the Jack Youden Prize for Best Expository Paper in Technometrics as well as the Frank Wilcoxon Award for Best Technical Paper. He received the 2005 COPSS Fisher Lecture and Award, the highest honor conferred by the statistics profession. He is a Fellow of the American Statistical Association and the Institute of Mathematical Statistics, and an elected member of the International Statistical Institute.
The KSU Alumni Fellowship program was established in 1983 to recognize distinguished alumni. Each year, faculty members from each of K-State’s colleges nominate alumni that they believe deserve the title of Alumni Fellow. The dean of each college then makes the final decision and the person selected is invited to be a part of a three-day celebration in their honor. Events usually include a cocktail party at the president’s home, classroom visits, speaking during a luncheon or at an educational panel, and a dinner with all fellows and their families. This year, Alumni Fellows will be on campus April 6-8.
Goh and Higgins Receive Faculty Enhancement Awards
Gyuhyeong Goh and Mike Higgins have each won an award in the Arts & Sciences Faculty Enhancement Program. This program was established in 2011 to promote independent research among new faculty members, consistent with K-State's Vision 2025 goals.
Gyuhyeong Goh plans to study Bayesian Functional Regression Modeling of Transcriptional Regulatory Networks. Understanding gene regulatory networks is a highly significant problem to interpret the phenotypic consequences (e.g. disease) of genetic variation. The study of transcriptional regulatory mechanism, however, involves several difficulties. First, it is hard to directly measure the actual activity of transcription factors due to the lack of technology. Second, a small number of transcription factors, that are significantly related to a given biological process, should be identified from a large pool of candidates, often referred to as sparse high-dimensional problems. Third, since a biological process is dynamic, it requires a time-course investigation into the temporal behavior of transcription factors during the biological process rather than at a single time point. In this project, our major goal is to develop a functional regression method to unveil the hidden transcriptional regulatory networks from a Bayesian perspective. The Bayesian approach enables us to incorporate prior knowledge about relevant transcription factors into a posterior inference procedure. The proposed project will broaden and deepen our understanding about transcriptional regulatory networks by providing us a general tool to investigate the consequences of genetic variation.
Mike Higgins plans to study Extensions of Threshold Blocking to Problems in Big Data and Causal Inference. Threshold blocking for an experiment is the process of grouping similar units together before assigning treatment so that each group contains at least a pre-specified number of units. Previous work involved developing a highly efficient algorithm for generating an approximately optimal threshold blocking in massive experiments. For example, using our method, experiments with 10 million units can be blocked in seconds using a personal computer. This project involves extending this procedure to other problems in Causal Inference and Big Data. We apply our method to the problem of finding regions of covariate overlap between treatment groups in observational studies. We also investigate the use of our algorithm as a data preprocessing technique to improve performance of prediction and clustering algorithms in massive datasets.
Du and Song Receive Faculty Development Awards
Juan Du and Weixing Song have each received a Faculty Development Award from the Office of Vice President for Research for Fall 2015.
