%description
How can we measure how the usage or frequency of some feature, such as
words, differs across some group or set, such as documents? One option is
to use the log odds ratio, but the log odds ratio alone does not account
for sampling variability; we haven't counted every feature the same number
of times so how do we know which differences are meaningful? Enter the
weighted log odds, which 'tidylo' provides an implementation for, using
tidy data principles. In particular, here we use the method outlined in
Monroe, Colaresi, and Quinn (2008) <doi:10.1093/pan/mpn018> to weight the
log odds ratio by a prior. By default, the prior is estimated from the
data itself, an empirical Bayes approach, but an uninformative prior is
also available.
