Compute ||theta - theta_hat|| distance for all parameters across iterations. This provides a single measure of convergence combining all parameters.
Usage
get_parameter_distance(
trajectories,
true_values,
norm_type = "euclidean",
chain_summary = "mean"
)Arguments
- trajectories
ngme_trajectories object from get_trace_trajectories()
- true_values
named list or vector of true parameter values
- norm_type
character, type of norm to use: "euclidean" (default), "manhattan", "max"
- chain_summary
character, how to summarize across chains: "mean" (default), "median", "chain1"
