%description
Estimates the authors or speakers of texts. Methods developed in Huang,
Perry, and Spirling (2020) <doi:10.1017/pan.2019.49>. The model is built
on a Bayesian framework in which the distinctiveness of each speaker is
defined by how different, on average, the speaker's terms are to everyone
else in the corpus of texts. An optional cross-validation method is
implemented to select the subset of terms that generate the most accurate
speaker predictions. Once a set of terms is selected, the model can be
estimated. Speaker distinctiveness and term influence can be recovered
from parameters in the model using package functions. Once fitted, the
model can be used to predict authorship of new texts.
