An Investigation of Goodness of Model Data Fit

open access: yesProcedia - Social and Behavioral Sciences, 2013
AbstractIRT models have many advantages over CTT. However, the model-data fit should be verified as a prerequisite to use IRT models. Therefore, in this study it is aimed to investigate which IRT model will provide the best fit to the data obtained from SBS 2009 science subtest.

Model data fit comparison between DINA and G-DINA in cognitive diagnostic models [PDF]

open access: yesEducation Journal, 2013
In this study, item and model data fit indices, calculated by DINA and G-DINA Models using the same sample and Q matrix, are analyzed. Fit indices for these two models from Cognitive Diagnostic Models are analyzed using 2LL, AIC and BIC statistics. Item fit indices are analyzed using residual correlations and probabilities.

A Study of Count Regression Models for Mortality Rate

open access: yesCauchy: Jurnal Matematika Murni dan Aplikasi, 2021
This paper discusses how overdispersed count data to be fit. Poisson regression model, Negative Binomial 1 regression model (NEGBIN 1) and Negative Binomial regression 2 (NEGBIN 2) model were proposed to fit mortality rate data.
