• logit.py create and fit a Plackett-Luce logit model. Written by Kiran Tomlinson.
• data_utils.py utility functions to read and process the state narcissism data.
• calculate_bounds.py generate baseline and tightened consideration probability bounds.
• state_bounds_demo.py replicates the calculations of consideration probability bounds for the 50 U.S. states from the Putnam dataset.

1. Copy State Narcissism Scrubbed Data.csv from Putnam et al, 2018 into data/
2. Run state_bounds_demo.py to display initial and tightened lower and upper bounds on consideration probabilities for each state, sorted in descending order of final upper bound.
