In idealstan: Robust Measurement with 'Stan'

Residual function for checking estimated samples compared to true simulation scores Returns a data frame with residuals plus quantiles.

Description

Residual function for checking estimated samples compared to true simulation scores Returns a data frame with residuals plus quantiles.

Usage

id_sim_resid(obj, rep = 1)

Arguments

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

Value

A named list of tibble objects, one per parameter type (Ideal Points, Absence Discrimination, Item Discrimination), each with columns avg, high, low, Params, est_type, and iter summarising posterior residuals 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_resid(est)
