Bayesian supervised topic modeling with covariates
The temporal and financial resources needed to qualitatively analyze textual data can be prohibitive. However, a growing collection of quantitative modeling approaches for text offer potential alternatives. One latent variable approach, topic modeling, assumes that text can be summarized as a mixture of latent categories (i.
