Specify a Binary Model with a Separate Interaction Prior — specify_binary_model_with_interaction

Retains the approved binary model contract while recording a common main-effect prior scale and a narrower coefficient-specific interaction prior scale.

Usage

specify_binary_model_with_interaction_prior(
  prepared,
  baseline,
  intercept_scale = 1.5,
  main_effect_scale = 0.75,
  interaction_scale = 0.5,
  group_sd_scale = 1,
  correlation_eta = 2,
  student_df = 3
)

Arguments

prepared: A gp3bayes_binary_prepared object containing one approved two-way interaction.
baseline: Plausible baseline event probability.
intercept_scale: Intercept-prior scale.
main_effect_scale: Common population main-effect prior scale.
interaction_scale: Interaction prior scale.
group_sd_scale: Group-level standard-deviation prior scale.
correlation_eta: LKJ shape.
student_df: Student-t degrees of freedom.

Value

A binary model specification with advanced prior metadata.
