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.

Application of the Two-Scale Model to the HERMES Data on Nuclear Attenuation [PDF]
, 2004 The Two-Scale Model and its improved version were used to perform the fit to the HERMES data for $\nu$ (the virtual photon energy) and z (the fraction of $\nu$ carried by hadron) dependencies of nuclear multiplicity ratios for $\pi^+$ and $\pi ...

An Online Test for Goodness-of-Fit in Logistic Regression Model
IEEE Access, 2019 In past decades, the goodness-of-fit test has been widely used to evaluate the calibration of prediction models. The test helps to determine whether poor predictions (lack of fit) are significant, which would indicate that problems exist in the model ...

SI epidemic model applied to COVID-19 data in mainland China [PDF]
Royal Society Open Science, 2020 The article is devoted to the parameters identification in the SI model. We consider several methods, starting with an exponential fit to the early cumulative data of SARS-CoV2 in mainland China.

Two Component Model of Dark Energy
, 2007 We consider the possibility that the dark energy is made up of two or more independent components, each having a different equation of state. We fit the model with supernova and gamma-ray burst (GRB) data from resent observations, and use the Markov ...

A Consistent model of Electroweak data including $Z\to b\overline{b}$ and $Z\to c \overline{c}$
, 1996 We have performed an overall fit to the electroweak data with the generation blind $U(1)$ extension of the Standard Model. As input data for fitting we have included the asymmetry parameters, the particle decay widths of $Z$, neutrino scattering, and ...

Square : Journal of Mathematics and Mathematics Education, 2022 The study determined if the 1PL, 2PL, 3PL and 4PL item response theory models best fit the data from the 2016 NECO Mathematics objective tests. Ex-post facto design was adopted for the study. The population for the study comprised 1,022,474 candidates who enrolled and sat for June/July SSCE 2016 NECO Mathematics Examination.
