Estimate a Design-Standardised Binary Probability Contrast — estimate_standardized_probability

Replaces the focal-condition value across a declared target covariate distribution, obtains population-level expected probabilities using brms::posterior_epred(), and averages within each posterior draw.

Usage

estimate_standardized_probability_contrast(
  fit,
  target_data = NULL,
  target_scale = c("prepared", "raw"),
  ndraws = NULL,
  include_group_effects = FALSE
)

Arguments

fit: An approved gp3bayes binary fit.
target_data: Optional target covariate distribution.
target_scale: Whether supplied target data are raw or already prepared.
ndraws: Optional number of posterior draws.
include_group_effects: Whether recorded group-level effects are included. The default FALSE targets population-level predictions.

Value

A gp3bayes_estimand with probability-difference draws.
