Determining factors influencing middle school teachers in demonstrating test score inflation

International Journal of Assessment Tools in Education
This study examines the determinants of test score inflation among middle school teachers within Türkiye’s exam-driven education system. Test score inflation -defined as increasing students’ scores beyond actual performance due to internal or external ...

A score test for zero‐inflation in correlated count data [PDF]

Statistics in Medicine, 2005
AbstractTo account for the preponderance of zero counts and simultaneous correlation of observations, a class of zero‐inflated Poisson mixed regression models is applicable for accommodating the within‐cluster dependence. In this paper, a score test for zero‐inflation is developed for assessing correlated count data with excess zeros.

A score‐type test for heterogeneity in zero‐inflated models in a stratified population [PDF]

Statistics in Medicine, 2014
AbstractWe propose a score‐type statistic to evaluate heterogeneity in zero‐inflated models for count data in a stratified population, where heterogeneity is defined as instances in which the zero counts are generated from two sources. Evaluating heterogeneity in this class of models has attracted considerable attention in the literature, but existing ...

Admission lactate level and the GRACE 2.0 score are independent and additive predictors of 30-day mortality of STEMI patients treated with primary PCI-Results of a real-world registry.

PLoS ONE, 2022
BackgroundIn many of the risk estimation algorithms for patients with ST-elevation myocardial infarction (STEMI), heart rate and systolic blood pressure are key predictors.

REMOTE Ischemic Perconditioning Among Acute Ischemic Stroke Patients in Catalonia: REMOTE-CAT PROJECT

Frontiers in Neurology, 2020
Rationale: Remote ischemic perconditioning during cerebral ischemia (RIPerC) refers to the application of brief episodes of transient limb ischemia commonly to a limb, it represents a new safe, simple and low-cost paradigm in neuroprotection.Aim and/or ...

Improving the validity of Script Concordance Testing by optimising and balancing items [PDF]

, 2018
Background: A script concordance test (SCT) is a modality for assessing clinical reasoning. Concerns had been raised about the plausible validity threat to SCT scores if students deliberately avoided the extreme answer options to obtain higher scores ...

A study of the score test in discrimination poisson and zero-inflated poisson models [PDF]

Acta Scientiarum. Technology, 2013
In many experimental situations the sample may present excess zero observations and generally are used probabilistic models for zero inflated to represent them. However no one knows precisely the amount of zero observations that these models support. Depending on the sample size and null observations number the Poisson model can be used.

Analysis of Count Data by Transmuted Geometric Distribution

Journal of Statistical Theory and Applications (JSTA), 2019
Transmuted geometric distribution (TGD) was recently introduced and investigated by Chakraborty and Bhati [Stat. Oper. Res. Trans. 40 (2016), 153–176]. This is a flexible extension of geometric distribution having an additional parameter that determines ...

Item Response Modeling of Multivariate Count Data With Zero Inflation, Maximum Inflation, and Heaping [PDF]

, 2017
Questionnaires that include items eliciting count responses are becoming increasingly common in psychology. This study proposes methodological techniques to overcome some of the challenges associated with analyzing multivariate item response data that ...
