In order to execute code for publicly available ECPE or TIMSS dataset, please execute RMD file DINA_2_bootstrap_ECPE.Rmd or DINA_2_bootstrap_TIMSS.Rmd respectively. The UTD Social Psychology data used as part of this study is not made publicly available hence DINA_2_bootstrap_SocialPsychology.Rmd cannot be executed. Also, the n_boot parameter in calculate_parameters.R file should be set to 10 during Development Phase in order to avoid longer execution times.
