The tree of political violence: a GMERT analysis

  • Thomas Bassetti
  • Raul Caruso
  • Friedrich Schneider


The aim of this article is to highlight that some economic correlates of Islamist political violence matter differently when they are considered in a specific path. In order to show this, we use a Generalized Mixed Effects Regression Tree analysis. This methodology combines the structure of random effects models for longitudinal data with the flexibility of a tree regression method. The latter is a nonparametric method for estimating a regression function.
