Power analysis for RNA-Seq differential expression studies

open access: yesBMC Bioinformatics, 2017
Background Sample size calculation and power estimation are essential components of experimental designs in biomedical research. It is very challenging to estimate power for RNA-Seq differential expression under complex experimental designs.

Empirical likelihood inference and goodness-of-fit test for logistic regression model under two-phase case-control sampling

open access: yesStatistical Theory and Related Fields, 2022
Due to cost-effectiveness and high efficiency, two-phase case-control sampling has been widely used in epidemiology studies. We develop a semi-parametric empirical likelihood approach to two-phase case-control data under the logistic regression model. We

The Likelihood Ratio Test and Full Bayesian Significance Test under small sample sizes for contingency tables

open access: yes, 2017
Hypothesis testing in contingency tables is usually based on asymptotic results, thereby restricting its proper use to large samples. To study these tests in small samples, we consider the likelihood ratio test and define an accurate index, the P-value ...

Hierarchical image segmentation relying on a likelihood ratio test [PDF]

open access: yes, 2015
International audienceHierarchical image segmentation provides a set of image seg-mentations at different detail levels in which coarser details levels can be produced by simple merges of regions from segmentations at finer detail levels.

Inflated Kumaraswamy distributions

open access: yesAnais da Academia Brasileira de Ciências, 2019
: The Kumaraswamy distribution is useful for modeling variables whose support is the standard unit interval, i.e., (0, 1). It is not uncommon, however, for the data to contain zeros and/or ones.

Detecting level shifts in the presence of conditional heteroscedasticity. [PDF]

open access: yes, 2003
The objective of this paper is to analyze the finite sample performance of two variants of the likelihood ratio test for detecting a level shift in uncorrelated conditionally heteroscedastic time series.

Type-1 Beta Distribution and its Connections to Likelihood Ratio Test

open access: yesStatistica
In many cases involving hypothesis testing for parameters in multivariate Gaussian populations and certain other populations, likelihood ratio criteria, or their one-to-one functions, can be expressed in terms of the determinant of a real type-1 beta ...

Assessment of a modification of Brückner′s test as a screening modality for anisometropia and strabismus

open access: yesOman Journal of Ophthalmology, 2010
Background : Current amblyopia screening methods are not cost effective. Aim : To evaluate the diagnostic capability of a modified Brückner test (MBT) for amblyopiogenic risk factors.

An information-theoretic approach to the gravitational-wave burst detection problem [PDF]

open access: yes, 2017
The observational era of gravitational-wave astronomy began in the Fall of 2015 with the detection of GW150914. One potential type of detectable gravitational wave is short-duration gravitational-wave bursts, whose waveforms can be difficult to predict ...
