Comparing Bayesian spatial models: Goodness-of-smoothing criteria for assessing under- and over-smoothing.

open access: yesPLoS ONE, 2020
BACKGROUND:Many methods of spatial smoothing have been developed, for both point data as well as areal data. In Bayesian spatial models, this is achieved by purposefully designed prior(s) or smoothing functions which smooth estimates towards a local or ...

On the Sequential Hierarchical Cognitive Diagnostic Model

open access: yesFrontiers in Psychology, 2020
Model data fit plays an important role in any statistical analysis, and the primary goal is to detect the preferred model based on certain criteria. Under the cognitive diagnostic assessment (CDA) framework, a family of sequential cognitive diagnostic ...

The inert doublet model in the light of Fermi-LAT gamma-ray data: a global fit analysis

open access: yesEuropean Physical Journal C: Particles and Fields, 2017
We perform a global fit within the inert doublet model taking into account experimental observables from colliders, direct and indirect dark matter searches and theoretical constraints.

Goodness of fit in models for mortality data [PDF]

open access: yes, 2008
Mortality data on an aggregate level are characterized by very large sample sizes. For this reason, uninformative outcomes are evident in common Goodness-of-Fit measures.

An Online Test for Goodness-of-Fit in Logistic Regression Model

open access: yesIEEE 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 ...
