%description
Extend the 'tidymodels' ecosystem <https://www.tidymodels.org/> to enable
the creation of predictive models with offset terms. Models with offsets
are most useful when working with count data or when fitting an adjustment
model on top of an existing model with a prior expectation. The former
situation is common in insurance where data is often weighted by
exposures. The latter is common in life insurance where industry mortality
tables are often used as a starting point for setting assumptions.
