Can Item and Person Estimates be Imported into RUMM2030?


RUMM2030 allows for importing of item estimates through its anchor items routine and of person estimates through the creation of a New Project. These procedures are related as follows:

NOTE: The one thing you must be very careful of when importing items and persons is to have them checked in terms of the strict requirements imposed by the measurement model. RUMM2030 does all this routinely when the normal procedures are invoked; the anchor items facility is a good way of achieving this outcome. The persons must also be checked thoroughly before conducting a Rasch analysis and RUMM2030 does this in the editing and sufficient statistics stages which occur prior to the estimation routines. By using the sequence outlined above all of the necessary checks and balances are engaged. The procedure is really straight forward and does not involve much effort overall.
