R Documentation

RMSE function for calculating individual RMSE values compared to true simulation scores Returns a data frame with RMSE plus quantiles.

Description

RMSE function for calculating individual RMSE values compared to true simulation scores Returns a data frame with RMSE plus quantiles.

Usage

id_sim_rmse(obj, rep = 1)

Arguments

`obj`	A fitted `idealstan` object with true data from `id_sim_gen()`
`rep`	Over how many replicates to calculate RMSE? Currently can only be 1

Value

A named list of tibble objects, one per parameter type (Ideal Points, Absence Discriminations, Item Discrimations), each with columns avg, high, low, Params, est_type, and iter summarising RMSE relative to true parameter values.

Examples


sim <- id_sim_gen()
est <- id_estimate(sim, model_type=1, fixtype='vb_full',
                   use_method="pathfinder", nchains=2, ncores=2)
id_sim_rmse(est)
