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 ...

Score test variable screening. [PDF]
Biometrics, 2014 SummaryVariable screening has emerged as a crucial first step in the analysis of high‐throughput data, but existing procedures can be computationally cumbersome, difficult to justify theoretically, or inapplicable to certain types of analyses. Motivated by a high‐dimensional censored quantile regression problem in multiple myeloma genomics, this ...

Circulation, 2006 Nonparametric statistical methods are useful tools for data analysis when there is reason to believe that the outcome variables of interest may fail certain distributional assumptions required for parametric methods. Variables may be ordered categories in nature and thereby not suitable for analysis methods that assume normally distributed variables ...

Generalised Score and Wald Tests [PDF]
Advances in Decision Sciences, 2010 The generalised score and Wald tests are described and related to their nongeneralised versions. Two interesting applications are discussed. In the first a new test for the Behrens-Fisher problem is derived. The second is testing homogeneity of variances from multiple univariate normal populations.

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 ...

Team Performance with Test Scores [PDF]
Proceedings of the Sixteenth ACM Conference on Economics and Computation, 2015 Team performance is a ubiquitous area of inquiry in the social sciences, and it motivates the problem of team selection —choosing the members of a team for maximum performance. Influential work of Hong and Page has argued that testing individuals in isolation and then assembling the highest scoring ones into a team ...

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.
