Determinants of Medical Resources in the U.S.: a County-level Econometric Analysis
by Yunxin Wu, Xu Wang, Daniela Alvarez
Xu, Yunxin, and Daniela collaborated together in the WiDS Datathon Phase II. Xu and Yunxin have known each other for 20 years. Xu is pursuing his PhD in economics and Yunxin is developing her career in the domains of technology, research, data science, and business management, and aspires to further her career in interdisciplinary research. When Yunxin met Daniela during the Datathon office hours, they found common interests in exploring the COVID track. Daniela is a self-taught data scientist from Peru who is eager to participate in Phase II as her first experience in research.
The team collaborated well together. Xu led the project by applying his PhD knowledge and tools to formalize the research question, design empirical strategies, perform statistical analysis and professionally present the findings. Yunxin researched external datasets, helped select and focus the research topic, used data science techniques and customized non-conventional variables. She appreciates the opportunity in academic writing, data analysis, visualization, and augmentation, as well as networking, learning different coding habits and styles, and various version control methods. Daniela contributed to data cleaning, exploration and preliminary analysis using machine learning tools. She landed her new data science job during the datathon, as well, and this experience positively impacted her career direction. She says,
“You don’t need to be a machine learning engineer or a data scientist to contribute, and everyone can contribute with their expertise and learn machine learning skills to help within their own fields” -- Daniela Alvarez
The team believes that research is not all about prediction accuracy; it is about quantitative thinking. It was a great learning experience to gain both research skills, and opportunities for teamwork and collaboration. Xu realizes that collaborating on a project requires much soft skills and team camaraderie and that participating in the WiDS Datathon Phase II was “good practice making mistakes and a great sandbox to learn.”

Automatic PM2.5 Prediction Including Feature Engineering and Model Tuning
by Olivia Zhao
Olivia Zhao, a rising senior at Chapel Hill High School, had a small amount of data science exposure through her high school course. When a teacher at her school shared the opportunity, the WiDS Datathon Phase II piqued her interest, as she would have more freedom to explore the data rather than set on a specific path. It was a challenge, indeed, which felt daunting at first.
Olivia persisted by looking at previous examples of prior Phase II papers. She was intrigued by the EPA dataset, as it related to the topics she was learning in her earth science class. She wanted to learn how people worked with this pollutant in data science and how data science can be applied to real-life questions, instead of simply numbers and tables.
To Olivia, the WiDS Datathon Phase II clarified how people use data science in real life. She is now considering data science as a career path to pursue.

You Have to Pay Attention to the Road Even if You Don't Know Where You're Going
by Christine Kuta, Aissatou Cissoko Diallo, Drashti B. Desai
Christine, Aissatou, and Drashti collaborated across Massachusetts and New Jersey. They each had an expertise to bring to the table: Aissatou was the programmer; Drashti was the data visualizer; and Christine was the engineer.
New to data science, both Aissatou and Drashti were initially hesitant to participate but persevered. Aissatou says, “We saw where we were struggling, and what we had to do to overcome it. As a newbie you are always shy, but you can get over it. People will catch you when you need it. Even when it is intimidating, you can do it.” Drashti responds, “there is a notion that you cannot do it. You have to learn by going, and by doing it.”
They were pleased with their outcome, and learned a lot from each other. Aissatou says that the datathon helped her build the gap between being a confused new graduate to being more confident to apply for an entry level data scientist role and feeling ready for it, saying, “I am no longer afraid of data science”. Drashti applied what she learned in Phase II to her master’s degree in business analysis. She realizes that data science is more than coding, modeling, and predictive analysis; it is also about gaining insights. Christine has been studying data science as an addition to her existing knowledge and skills, and her WiDS experience has helped her gain a new level of confidence in exploring data science opportunities.
The team, which met virtually through WiDS, is now completing a new project together working on an analysis of the economic factors and impact of the environment.

An evaluation of hazardous air pollutants in diverse demographic groups across United States
by Lesley Chapman Hannah
Lesley Chapman Hannah learned about the WiDS Datathon through a notice sent out through her graduate department at American University. Lesley does research for a living. As a postdoc at the National Cancer Institute (NCI), she studies health related questions and applies machine learning to research questions. When deciding which track for WiDS Datathon Phase II to pursue, the EPA dataset seemed to be a natural extension of the WiDS Datathon focus on climate change.
Lesley’s interests aligned with the focus of Phase II this year on open-ended exploration. She enjoys looking at every aspect of a project, researching, and applying a chosen method. She has been wanting to try out this statistical approach in other facets, so the WiDS Datathon Phase II was a great place to start. Lesley has enjoyed learning and gaining new skills this year through the WiDS Datathon 2022.
