plot_imi_check: Visualize IMI scores for the top words in topics

In agoldst/dfrtopics: Tools for exploring topic models of text

Visualize IMI scores for the top words in topics

Description

As a diagnostic visualization, this function displays the IMI scores of the top-weighted words in a topic, together with simulated values, on a scale set by the distribution of simulated values. Extreme deviations of the actual IMI scores indicate departures from the multinomial assumption of the model.

Usage

plot_imi_check(m, k, groups = NULL, n_reps = 20, ...)

Arguments

m	mallet_model object with sampling state loaded via load_sampling_state
k	topic number (only one topic at a time)
groups	optional grouping factor with one element for each document
n_reps	number of simulations
...	passed on to top_words: use to specify number of top words and/or weighting function

Value

ggplot2 plot object
