A Comparison of Item- and Person-Fit Methods of Assessing Model-Data Fit in IRT [PDF]
Applied Psychological Measurement, 1990 Many item-fit statistics have been proposed for assessing whether the responses to test items ag gregated across examinees conform to IRT test models. Conversely, person-fit statistics have been proposed for assessing whether an examinee's re sponses aggregated across items are congruent with a specified IRT model.

A Study of Count Regression Models for Mortality Rate
Cauchy: 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.

A goodness of fit measure related to r² for model performance assessment [PDF]
, 2013 Checking the predictive worth of an environmental model inevitably includes a goodness of fit metric to quantify the degree of matching to recorded data, thereby giving a measure of model performance. Considerable analysis and discussion have taken place

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