XSPEC model for testing the Kerr black hole hypothesis using the continuum-fitting method [PDF]

open access: yesPhysical Review D, 2019
We present NKBB, an XSPEC model for the thermal spectrum of thin accretion disks in parametric black hole spacetimes. We employ the Novikov-Thorne model for the description of the accretion disk and the formalism of the transfer function proposed by ...

THE INFLUENCE OF AUGMENTED REALITY MEDIA TO IMPROVE UNDERSTANDING CONCEPTS IN SOCIAL STUDIES LEARNING IN ELEMENTARY SCHOOLS

open access: yesMuallimuna: Jurnal Madrasah Ibtidaiyah
This research aims to determine the effect of using augmented reality media on increasing understanding of social studies learning concepts in elementary schools. This research is a quantitative research with a quasi-experimental design, namely a type of

Bootstrap methods for multivariate hypothesis testing

open access: yesCommunications in statistics. Simulation and computation, 2017
The nonparametric and parametric bootstrap methods for multivariate hypothesis testing are developed. They are used to approximate the null distribution of the test statistics proposed by Duchesne and Francq (2015), resulting in bootstrap testing ...

Simulation‐based hypothesis testing of high dimensional means under covariance heterogeneity [PDF]

open access: yesBiometrics, 2014
In this article, we study the problem of testing the mean vectors of high dimensional data in both one‐sample and two‐sample cases. The proposed testing procedures employ maximum‐type statistics and the parametric bootstrap techniques to compute the ...

Model Averaging with AIC Weights for Hypothesis Testing of Hormesis at Low Doses

open access: yesDose-Response, 2017
For many dose–response studies, large samples are not available. Particularly, when the outcome of interest is binary rather than continuous, a large sample size is required to provide evidence for hormesis at low doses. In a small or moderate sample, we

Unified Lowering Decision of Parametric Thinning in the Hypothesis Test Framework

open access: yes2015 International Conference on Digital Image Computing: Techniques and Applications (DICTA), 2015
Homotopic grayscale thinning leads to over-connected skeleton when applied on noisy images. To avoid this phenomenon, the parametric thinning relaxes the initial constraint by lowering low contrast crests, peaks and ends, according to a parameter related to the noise and contrast of the image and under the constraint of ascendant gray level processing.

Bayesian Model Comparison in Genetic Association Analysis: Linear Mixed Modeling and SNP Set Testing [PDF]

open access: yes, 2015
We consider the problems of hypothesis testing and model comparison under a flexible Bayesian linear regression model whose formulation is closely connected with the linear mixed effect model and the parametric models for SNP set analysis in genetic ...

General Semiparametric Shared Frailty Model: Estimation and Simulation with frailtySurv

open access: yesJournal of Statistical Software, 2018
The R package frailtySurv for simulating and fitting semi-parametric shared frailty models is introduced. Package frailtySurv implements semi-parametric consistent estimators for a variety of frailty distributions, including gamma, log-normal, inverse ...

Differential mitochondrial toxicity screening and multi-parametric data analysis. [PDF]

open access: yesPLoS ONE, 2012
Early evaluation of new drug entities for their potential to cause mitochondrial dysfunction is becoming an important task for drug development. Multi-parametric high-content screening (mp-HCS) of mitochondrial toxicity holds promise as a lead in-vitro ...
