资源简介：
This R Code is used with the Item_bank_eggen_verschoor data. This is to create simulated data with differing levels of test difficulty. Test difficulty is modified by changing the R syntax. The current code creates simulated data for a very easy test (90% correct). The easy test was created through modifying the R-Code to "tpc=2.197" line. This is an item selection parameter and measured in logits. For a more difficult test, change "tpc=2.197" to say "tpc=.451." The study associated with this data is "Self-Efficacy in the CAT Environment."
