The modeled, REALSE=N, standard errors of measure estimates (abilities and difficulties) are the smallest possible errors. These always overstate the measurement precision.

 

Controls the reporting of standard errors of measures in all tables.

 

REALSE=N

Report modeled, asymptotic, standard errors (the standard).

 

REALSE=Y

Report the modeled standard errors inflated by the square root of the infit mean square, when it is greater than 1.0. This inflates the standard error to include uncertainty due to overall lack of fit of data to model.

 

See Standard Errors: Model and Real for more details.
