So excited to see my first solo-authored paper in English officially accepted!

Stay tuned for more research on crime, institutions, and quantitative methods

While these analyses are predictive and not intended to establish causal relationships, I also employ feature importance analysis to reveal the main drivers of police and military violence in both countries

The study combines Lasso, Random Forests, XGBoost, Neural Networks, and a Super Learner ensemble to anticipate misconduct by the military and police at the municipal level. #MilitaryMisconduct

Using detailed subnational data from Colombia and Mexico, I built several machine learning models to predict violence by armed forces, achieving over 92% accuracy 📈 #PoliceViolence

Aunque los análisis son predictivos y no buscan establecer relaciones causales, también miro la importancia de variables para identificar los principales factores que explican la violencia en ambos países
