Statistics Building

Welcome to the Department of Statistics at Colorado State University. Statistics is the science of inferring knowledge from data and describing uncertainty in those inferences. It plays a central role in scientific research, social policy, and governance. The Department of Statistics has a world-class record of success in education, research and service and has an out-sized impact on campus because of its engagement in educating students in all disciplines and interdisciplinary research.


Department Highlights

Undergraduate Summer Research

This summer 14 Statistics and Data Science undergraduates gained valuable experience by participating in research projects.  These paid positions are sponsored by the College of Natural Sciences, the Statistics department and the Data Science program.  Students were supervised by faculty members Yawen Guan, Ann Hess, Dongzhou Huang, Kayleigh Keller, Aaron Nielsen, Ben Prytherch, Ben Shaby, Tianying Wang, Yunpeng Zhao and Tianjian Zhou.  Application areas included fire conditions in the Western US, football analytics, statistical learning in cancer genomics, quantum computing and homeless outreach in Fort Collins.  Students presented their work to the department on June 28.  This is the third year the department has offered this popular program.  Eight participating students from summer 2023 presented at Celebrate Undergraduate Research and Creativity (CURC) on April 18.


June 2024: Piotr Kokoszka has been awarded a 36 month Statistics program grant for the project “Monitoring time series in structured function spaces.” The project aims to develop new mathematical theory and statistical tools that will enable monitoring for changes in complex systems, for example in spatio-temporal patterns of infectious diseases, financial asset portfolios, or global trade networks. It will develop statistical methods for  making decisions about an emergence of an atypical pattern in a complex system in real time and with statistical guarantees of a correct decision. The project will also offer multiple interdisciplinary training opportunities for the next generation of statisticians and data scientists, and will include collaborations with economists in the United Kingdom.

Professor Andee Kaplan Receives NSF CAREER Grant

Andee Kaplan (PI) received NSF grant “CAREER: Flexible Record Linkage through Realistic Modeling of Dependent, Missing, and Updating Data.” Record linkage is the process of resolving duplicates in partially overlapping sets of records from noisy data sources without a unique identifier. This project will develop flexible Bayesian record linkage models to enable more accurate linking of data sets through development of flexible priors to incorporate dependence and account for realistic missingness. Additionally, this approach will allow for dynamic data via an updating querying framework for record linkage achieved through a novel filtering approach. This novel methodology will be applied to publicly available and Census Bureau data from the 19th century with identifying information about freedom seekers, captive individuals in the coastwise slave trade, and Black Americans in the Antebellum South. Official records of these individuals are fractured into many sources, each only giving a small glimpse in time. Applying the developed flexible Bayesian record linkage model, this research will reconstruct a fuller account of their lives through linking multiple noisy data sources. Graduate students will be mentored and software will be made publicly available.

2024 WNAR/IMS/Graybill Conference

The Department of Statistics will host the 2024 WNAR/IMS/Graybill Annual Meeting Sunday, June 9 through Wednesday, June 12. More information can be found here.

Piotr Kokoszka Selected as 2024 Professor Laureate

Professors Piotr Kokoszka (Statistics) and Olve Peersen (Biochemistry and Molecular Biology) have been recognized by the College of Natural Sciences as 2024 Professor Laureates.
The Professor Laureate Award is the college’s highest academic honor, bestowed upon dedicated faculty with outstanding contributions to the missions of research, teaching, mentoring and outreach. The designation is intended to honor recipients and to provide the college with exceptional role models. The title is held for three years and includes an honorarium and two years of research funding.

Workshop on Bayesian analysis of environmental data

September 18-20, 2023, our department will host a workshop on complex environmental data. Its aim is to provide researchers in  Bayesian, environmental and ecological statistics with a venue to share cutting-edge advances and spark deeper knowledge gains. The workshop will facilitate  the transfer of knowledge between research sub-communities, fostering collaboration, and encourage advances from the wider community of researchers in Bayesian analysis of complex datasets to percolate into the environmental domain.

The Data Science and Statistical Learning Journal Club

The Data Science and Statistical Learning Journal Club

The Data Science and Statistical Learning Journal Club meets weekly to discuss papers and current work on topics relevant to data science and statistical learning. At the beginning of each semester, we will select a few interesting and latest manuscripts to study.

See the Data Science and Statistical Learning Journal Club website here.

Stat Alliance

CSU Stat Alliance

Stat Alliance is a student-led club welcome to all students with any level of interest or skill in statistics. Our meetings include hearing from guest speakers in the field of statistics,  making connections, social activities and much more!

See the Stat Alliance website and full calendar of upcoming events here.

Environmental Biostatistics Working Group

Environmental Biostatistics Working Group

The Environmental Biostatistics Working Group seeks to build collaboration and community among faculty and students working in biostatistics with application in environmental and public health.

See the Environmental Biostatistics Working Group website here.

Statistics Communication Group

Statistics Communication Group

The Statistics Communication Group is a student-led platform for communicating statistics research to the public. Graduate and undergraduate students conducting statistics research can submit a short explanation of their research for publication on the writing group’s blog.

Department News

In memory: Peter Brockwell

Peter Brockwell passed away peacefully on July 5 in Melbourne, surrounded by his family. He was a faculty member in the Statistics Department for several decades, until his retirement, including an appointment as the department chair.

Likelihood of another fire season as bad as 2020 up to 10 times higher than it was 50 years ago, CSU research shows

The 2020 wildfire season may have been the worst in Colorado’s history, but if recent climate trends hold true, years like this could become more and more common. 

Statistics undergraduate summer research program culminates at CURC

For students studying statistics, undergraduate research is a valuable, hands-on chance to learn how to use statistics to support real research with real-world outcomes.

Washington County: Levi Kipp – Statistics

During the 2022-23 academic year, we are highlighting one Colorado State University student or alum from each of Colorado’s 64 counties. The Centennial State’s land grant university has a connection to the diverse lands and people from the counties of Moffat to Baca, Montezuma to Sedgwick and everywhere in between.
