On the uses and abuses of regression models: a call for reform of statistical practice and teaching [PDF]
arXiv, 2023 Regression methods dominate the practice of biostatistical analysis, but biostatistical training emphasises the details of regression models and methods ahead of the purposes for which such modelling might be useful. More broadly, statistics is widely understood to provide a body of techniques for "modelling data", underpinned by what we describe as ...

Journal of Indian Society of Periodontology, 2014 Background: Biostatistics is an integral part of research protocols. In any field of inquiry or investigation, data obtained is subsequently classified, analyzed and tested for accuracy by statistical methods. Statistical analysis of collected data, thus,

Signal Identification for Rare and Weak Features: Higher Criticism or False Discovery Rates? [PDF]
Biostatistics 2013, Vol. 14, 129-143, 2011 Signal identification in large-dimensional settings is a challenging problem in biostatistics. Recently, the method of higher criticism (HC) was shown to be an effective means for determining appropriate decision thresholds. Here, we study HC from a false discovery rate (FDR) perspective.

Gene profiling for determining pluripotent genes in a time course microarray experiment [PDF]
Biostatistics, Volume 10, Number 1, 2009, pages 80-93, 2008 In microarray experiments, it is often of interest to identify genes which have a pre-specified gene expression profile with respect to time. Methods available in the literature are, however, typically not stringent enough in identifying such genes, particularly when the profile requires equivalence of gene expression levels at certain time points.

Common pitfalls in statistical analysis: Measures of agreement
Perspectives in Clinical Research, 2017 Agreement between measurements refers to the degree of concordance between two (or more) sets of measurements. Statistical methods to test agreement are used to assess inter-rater variability or to decide whether one technique for measuring a variable ...
