Combine Posterior Simulations, Deterministic Prediction, and Observed Data for PPC Plotting

Combine Posterior Simulations, Deterministic Prediction, and Observed Data for PPC Plotting

Usage

prepare_ppc_data(ci_data, best_df, obs_df, sim_var, obs_var)

Arguments

ci_data

Data frame with posterior median and credible intervals. Must include date_ymd, variable, median, lower, and upper.

best_df

Long-format data frame from deterministic model run, including columns date_ymd, variable, and value.

obs_df

Wide-format observed data with columns date_ymd and obs_var.

sim_var

Character. Name of the variable used for simulated predictions (e.g., "inc_C_transformed").

obs_var

Character. Name of the observed variable in obs_df (e.g., "inc_C").

Value

A tibble combining observed, deterministic, and simulated prediction data, ready for plot_ppc().
