Summarise simulated data using various population comparison statistics

Source: R/functions.R

This collapses the simulation results within each condition to composite estimates such as RMSE, bias, Type I error rates, coverage rates, etc. See the See Also section below for useful functions to be used within Summarise.

Summarise(condition, results, fixed_objects)

Arguments

condition

a single row from the design input from runSimulation (as a data.frame), indicating the simulation conditions

results

a tibble data frame (if Analyse returned a named numeric vector of any length) or a list (if Analyse returned a list or multi-rowed data.frame) containing the analysis results from Analyse, where each cell is stored in a unique row/list element

fixed_objects

object passed down from runSimulation

Value

for best results should return a named numeric vector or data.frame with the desired meta-simulation results. Named list objects can also be returned, however the subsequent results must be extracted via SimExtract
