Core Pipeline

The three-step workflow: specify a design, add study conditions, and run the simulation.

irt_design(): Create an IRT Design Specification
irt_study(): Define Study Conditions for an IRT Simulation
irt_simulate(): Run an IRT Monte Carlo Simulation

Results Analysis

Summarize, visualize, and extract recommendations from simulation results.

summary(<irt_results>): Summarize IRT Simulation Results
plot(<irt_results>): Plot IRT Simulation Results
plot(<summary_irt_results>): Plot Summary of IRT Simulation Results
recommended_n(): Find the Minimum Sample Size Meeting a Criterion Threshold

Utilities

Helper functions for parameter generation and planning.

irt_params_2pl(): Generate 2PL Item Parameters
irt_params_grm(): Generate GRM Item Parameters
irt_iterations(): Compute Required Monte Carlo Replications
