Extract labelled kinetic parameters

Usage

posterior_parameters(
  x,
  level = c("population", "profile", "participant", "regression"),
  summary = TRUE,
  newdata = NULL,
  participants = NULL,
  ndraws = NULL,
  probs = c(0.025, 0.975),
  derived = TRUE
)

Arguments

x: An epikinetics_fit object.
level: One of "population", "profile", "participant", or "regression". Population output is the biomarker-specific model intercept. Profile output applies the fitted covariate effects to the conditional profiles from prediction_grid() or newdata, but excludes participant random effects.
summary: If TRUE, return means, medians, SDs, and intervals. If FALSE, return one labelled row per posterior draw.
newdata: Optional participant-level covariate profiles when level = "profile". NULL uses prediction_grid().
participants: Optional participant ids when level = "participant".
ndraws: Optional maximum number of posterior draws to use.
probs: Lower and upper interval probabilities.
derived: Include peak values, transition values, and waning half-lives.

Value

A tidy data frame. Summaries use one row per parameter and group; unsummarised results retain parameter columns and .draw. Regression output includes the original formula term, design-column name, and decoded treatment level/reference when the contrast has that interpretation.
