| Subject | st: calculating interval scores for a new sample when item and threshold parameters are known |
| Date | Fri, 4 Feb 2011 16:13:51 +0100 |
Dear statalists, I have performed an IRT analysis in STATA using gllamm on polytomous items resulting in estimates for the item difficulties and thresholds (same threshold estimates for all the items). Now I would like to use these item and threshold estimates for estimating the interval scores of persons (thetas) from a different sample who have also responded to the same questions. Is there anyone who could let me know whether that is possible in STATA and if so, how to go about that? Many thanks!
