%description
A one-function package containing prediction(), a type-safe alternative to
predict() that always returns a data frame. The summary() method provides
a data frame with average predictions, possibly over counterfactual
versions of the data (à la the margins command in 'Stata'). Marginal
effect estimation is provided by the related package, 'margins'
<https://cran.r-project.org/package=margins>. The package currently
supports common model types (e.g., lm, glm) from the 'stats' package, as
well as numerous other model classes from other add-on packages. See the
README file or main package documentation page for a complete listing.
