Contents and getting started

  • orig (directory containing the original simulation results)
  • repl (directory containing possible rerun simulation results)
  • replication.R (R code for the simulations, text results and figures)

To inspect the original simulation results, change the working directory in R to vuong_mirt_code/orig. To rerun the simulations, change it to vuong_mirt_code/repl. Finally, run the code in replication.R.
