Estimation of the Structural Topic Model
The Structural Topic Model (STM) allows researchers
to estimate topic models with document-level covariates.
The package also includes tools for model selection, visualization,
and estimation of topic-covariate regressions. Methods developed in
Roberts et al (2014) <doi:10.1111/ajps.12103> and
Roberts et al (2016) <doi:10.1080/01621459.2016.1141684>.
