Methodology, 2023 A shortcoming of least-squares unrestricted factor analysis (UFA) procedures, which are widely used in psychometric applications is that a test statistic for assessing model-data fit cannot be easily derived from the minimum fit function value.

A groupwise association test for rare mutations using a weighted sum statistic. [PDF]
PLoS Genetics, 2009 Resequencing is an emerging tool for identification of rare disease-associated mutations. Rare mutations are difficult to tag with SNP genotyping, as genotyping studies are designed to detect common variants.

Robust Test Statistic for Cooperative Spectrum Sensing Based on the Gerschgorin Circle Theorem
IEEE Access, 2018 The Gerschgorin circle theorem was recently applied to build two detectors for the purpose of spectrum sensing in cognitive radio applications, the so-called Gerschgorin radius-based and the Gerschgorin disk-based detectors.

Evaluating Structural Equation Models for Categorical Outcomes: A New Test Statistic and a Practical Challenge of Interpretation. [PDF]
Multivariate Behav Res, 2015 This research is concerned with two topics in assessing model fit for categorical data analysis. The first topic involves the application of a limited-information overall test, introduced in the item response theory literature, to structural equation ...

Ensuring Positiveness of the Scaled Difference Chi-square Test Statistic. [PDF]
Psychometrika, 2010 A scaled difference test statistic $\tilde{T}{}_{d}$ that can be computed from standard software of structural equation models (SEM) by hand calculations was proposed in Satorra and Bentler (Psychometrika 66:507–514, 2001). The statistic $\tilde{T}_{d}

EVALUATION OF A NEW MEAN SCALED AND MOMENT ADJUSTED TEST STATISTIC FOR SEM. [PDF]
Struct Equ Modeling, 2013 Recently a new mean scaled and skewness adjusted test statistic was developed for evaluating structural equation models in small samples and with potentially nonnormal data, but this statistic has received only limited evaluation. The performance of this

Verification, Testing and Statistics [PDF]
, 2009 Though formal verification has been the holy grail of software validation, practical applications of verification run into two major challenges. The first challenge is in writing detailed specifications, and the second challenge is in scaling verification algorithms to large software.
