drop_term

This function is needed to re-fit the models for Type III SS. If you have a model with an
interactive term (e.g. <code>y ~ a + b + a:b</code>), when you try to refit without one of the lower-order
terms (e.g. <code>y ~ a + a:b</code>) <code><a href="/link/lm()?package=supernova&version=2.5.3" data-mini-rdoc="supernova::lm()">lm()</a></code> will add it back in. This function uses a fitting function
that operates underneath <code><a href="/link/lm()?package=supernova&version=2.5.3" data-mini-rdoc="supernova::lm()">lm()</a></code> to circumvent this behavior. (It is very similar to <code><a href="/link/drop1()?package=supernova&version=2.5.3" data-mini-rdoc="supernova::drop1()">drop1()</a></code>.)

Produces ANOVA tables in the format used by Judd, McClelland,
and Ryan (2017, ISBN: 978-1138819832) in their introductory textbook,
Data Analysis. This includes proportional reduction in error and
formatting to improve ease the transition between the book and R.
