Frontiers in Genetics, 2021 Single cell RNA sequencing (scRNA-seq) allows quantitative measurement and comparison of gene expression at the resolution of single cells. Ignoring the batch effects and zero inflation of scRNA-seq data, many proposed differentially expressed (DE ...

Z Scores, Standard Scores, and Composite Test Scores Explained [PDF]
Indian Journal of Psychological Medicine, 2021 Patients may be assessed using a battery of tests where different tests yield scores in different units, where different tests have different minimum and maximum scores, and where higher or lower scores mean different things in different tests. Therefore, a composite test score cannot be obtained by simple addition or averaging of scores in the ...

Stroke, 2002 To the Editor: Hemphill et al1 present an analysis of 161 patients carried out to determine a reliable grading score for the prediction of 30-day mortality in patients following a spontaneous intracerebral hemorrhage (ICH). Factors independently associated with 30-day mortality were Glasgow Coma Score, age >80 years, ICH volume, ICH of infratentorial ...

Monte Carlo Test for Polynomial Covariates
Revstat Statistical Journal, 2012 In this paper, we review the score test procedure used for testing polynomial covariate effects in a semi parametric additive mixed model. This test is based on the mixed model representation of the smoothing spline estimator of the nonparametric ...

Distributions You Can Count On …But What’s the Point?
Econometrics, 2020 The Poisson regression model remains an important tool in the econometric analysis of count data. In a pioneering contribution to the econometric analysis of such models, Lung-Fei Lee presented a specification test for a Poisson model against a broad ...

A gene based combination test using GWAS summary data
BMC Bioinformatics, 2023 Background Gene-based association tests provide a useful alternative and complement to the usual single marker association tests, especially in genome-wide association studies (GWAS). The way of weighting for variants in a gene plays an important role in

Inflated Kumaraswamy distributions
Anais 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.
