Undergraduate Research Engagement Program (Spring 2016, Fall 2016, Spring 2017, Spring 2018)

The UREProgram at UMass partners advanced undergraduate political science and legal studies majors with faculty for hands-on, one-on-one research experiences. I have supervised over 20 undergraduate students for four different research projects. This involved training and mentoring them across all aspects of the research experience, including: developing research protocols, gathering and coding data, conducting literature reviews, and holding weekly mentoring meetings.

• Multinomial Logit Models in R For cases when the dependent variable has unordered categories, we use multinomial logit. For example, variable cc309 in the 2008 CESS (http://people.umass.edu/schaffne/cces08.dta) asks respondents ...

• Logit/Probit Models in R For this example, we'll use the 2008 Cooperative Congressional Election Study. You can download it here from Brian Schaffner's website (http://people.umass.edu/schaffne/cces08.dta). Download ...
