Researchers have developed a new moment-based inference method for regression analysis that utilizes latent Dirichlet covariates. This approach addresses inferential challenges arising from using topic model outputs as regression inputs, particularly the propagation of uncertainty from topic estimation. The method corrects for these issues by directly identifying regression coefficients without needing to estimate document-level topic shares, and it also identifies the unknown total concentration parameter of the Dirichlet distribution through operator commutativity.
