An Evaluation of Overall Goodness-of-Fit Tests for the Rasch Model

open access: yesFrontiers in Psychology, 2019
For assessing the fit of item response theory models, it has been suggested to apply overall goodness-of-fit tests as well as tests for individual items and item pairs.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Goodness-of-Fit Tests for Combined Unilateral and Bilateral Data

open access: yesMathematics
Clinical trials involving paired organs often yield a mixture of unilateral and bilateral data, where each subject may contribute either one or two responses.

Goodness-of-Fit Tests For Elliptical and Independent Copulas through Projection Pursuit

open access: yesAlgorithms, 2011
Two goodness-of-fit tests for copulas are being investigated. The first one deals with the case of elliptical copulas and the second one deals with independent copulas.

Bootstrap goodness-of-fit tests for farima models [PDF]

open access: yes, 1999
This paper proposes goodness-of-fit tests for the class of covariance stationary FARIMA processes. They are based on functionals of weighted empirical processes, say Sn C.), where the weights are the relative error between the periodogram and the fitted ...

Modelling stem cell differentiation related processes—A practical overview for biologists

open access: yesFEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Modified Goodness of Fit Tests for the Burr Distribution with Two Unknown Shape Parameters [PDF]

open access: yesThe Egyptian Statistical Journal, 1994
Goodness of fit tests are designed for checking the validity of a null hypothesis. This hypothesis is a statement about the form of the distribution function of the parent population from which the sample is drawn.

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

open access: yesMolecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

A best-fit probability distribution for the estimation of rainfall in northern regions of Pakistan

open access: yesOpen Life Sciences, 2016
This study was designed to find the best-fit probability distribution of annual maximum rainfall based on a twenty-four-hour sample in the northern regions of Pakistan using four probability distributions: normal, log-normal, log-Pearson type-III and ...
