Compensatory and non-compensatory multidimensional randomized item response models.
Randomized response (RR) models are often used for analysing univariate randomized response data and measuring population prevalence of sensitive behaviours. There is much empirical support for the belief that RR methods improve the cooperation of the respondents. Recently, RR models have been extended to measure individual unidimensional behaviour. An extension of this modelling framework is p...
متن کامل199-31: %MDIRT- FIT: SAS® Macros for Fitting Multidimensional Item Response
Even though unidimensional item response theory (IRT) provides a better framework for practical test settings than classical test theory (CTT), theoretical and empirical evidence shows that most response data violate the assumption of unidimensionality. There are several computer programs dedicated to estimating parameters based on the multidimensional perspective (MIRT). However, their accessi...
متن کاملAn unbiased model comparison test using cross-validation
Social scientists often consider multiple empirical models of the same process. When these models are parametric and non-nested, the null hypothesis that two models fit the data equally well is commonly tested using methods introduced by Vuong (Econometrica 57(2):307–333, 1989) and Clarke (Am J Political Sci 45(3):724–744, 2001; J Confl Resolut 47(1):72–93, 2003; Political Anal 15(3):347–363, 2...
متن کاملAssessing IRT Model-Data Fit for Mixed Format Tests
This study examined various model combinations and calibration procedures for mixed format tests under different item response theory (IRT) models and calibration methods. Using real data sets that consist of both dichotomous and polytomous items, nine possibly applicable IRT model mixtures and two calibration procedures were compared based on traditional and alternative goodnessof-fit statisti...
