Web17 de mar. de 2011 · An application of a hierarchical IRT model for items in families generated through the application of different combinations of design rules is discussed. Within the families, the items are assumed to differ only in surface features. The parameters of the model are estimated in a Bayesian framework, using a data-augmented Gibbs … WebWe performed IRT model three times using 1, 2 and 4 parameter models and compared their model fit indexes. The latent trait correlations estimated by these three models were very high (r = 0.98), suggesting that children's abilities did not change substantially when using the 4-parameter model.
