QSS DUR harnesses machine learning to analyze complex experimental designs

11/14/2017

Assistant Professor of Government Sean Westwood and coauthors recently released a new statistical method that harnesses machine learning to analyze complex experimental designs.  Their method was published in Political Analysis, the top methodology journal in political science.  With his colleagues, Westwood, the Director of Undergraduate Research in the Program in Quantitative Social Science, showed that it is possible to utilize a super-learner to estimate the effects of heterogenous treatments on respondents' attitudes.  Their method also allows for the analysis of heterogeneous responses to treatments.

David Cottrell is a postdoctoral fellow in the Program in Quantitative Science (QSS) and teaches the QSS course "By the Numbers: Race, Incarceration and Politics." Michael Herron is a visiting scholar at the Hertie School of Governance and professor of government at Dartmouth College. Sean Westwood is an assistant professor of government at Dartmouth College and teaches the QSS course "Computational Text Analysis."  As with their first analysis of voter fraud in the 2016 election, Cottrell, Herron, and Westwood find no evidence to support the assertions of large-scale voter fraud in New Hampshire that have been forthcoming from the Trump administration.
