Abstract | Investigated empirical Type I error rates and the power of omega (index of answer copying developed by J. Wollack, 1997) when item and trait (theta) parameters were unknown and estimated from datasets of 100 and 500 examinees. Type I error was unaffected by estimating item parameters, with power slightly lower for the smaller sample. (SLD) |
