.set_param

Unpacks the given expression to set the parameter specified by <code>which_param</code>
to <code>params</code>. Continues recursively setting parameters via
<code>.make_parameters()</code>.

internal

Quickly set and summarize contrasts for factors prior to regression analyses. Intended comparisons, baseline conditions, and intercepts can be explicitly set and documented without the user needing to directly manipulate matrices. Reviews and introductions for contrast coding are available in Brehm and Alday (2022)<doi:10.1016/j.jml.2022.104334> and Schad et al. (2020)<doi:10.1016/j.jml.2019.104038>.
