Summarize Simulations Results

summarize_sim(simulation_results, truth, ci_level = 0.95)



A data.frame, tibble or similar with exactly two columns named "param_est" and "param_var" giving the estimate of a parameter of interest and estimate of its variance (based on a valid variance estimator specific to that parameter).Each row of this data structure corresponds to the parameter estimate and variance for a single iteration of several simulations.


A numeric value giving the true value of the parameter of interest in the simulation setting.


A numeric value giving the level of the confidence intervals to be generated around the parameter estimates and statistics computed to summarize the simulation.
