Cet article concerne la modélisation de données incertaines à partir de mesures répétées mais non-reproductibles. Différentes approches issues des théories modernes de l'incertain sont considérées. Plus précisément, l'article s'intéresse à diverses extensions de tests statistiques non-paramétriques aux données incertaines. Dans ce travail prélimina...

BackgroundSWATH-MS has emerged as the strategy of choice for biomarker discovery due to the proteome coverage achieved in acquisition and provision to re-interrogate the data. However, in quantitative analysis using SWATH, each sample from the comparison group is run individually in mass spectrometer and the resulting inter-run variation may influe...

Conventional cardiovascular risk factors (CCVRFs) and carotid ultrasound image-based phenotypes (CUSIP) are independently associated with long-term risk of cardiovascular (CV) disease. In this study, 26 cardiovascular risk (CVR) factors which consisted of a combination of CCVRFs and CUSIP together were ranked. Further, an optimal risk calculator us...

We suggest twenty immediately actionable steps to reduce widespread inferential errors related to “statistical significance testing.” Our propositions refer to the theoretical preconditions for using p-values. They furthermore include wording guidelines as well as structural and operative advice on how to present results, especially in research bas...
The device-independent approach to physics is one where conclusions about physical systems (and hence of Nature) are drawn directly and solely from the observed correlations between measurement outcomes. This operational approach to physics arose as a byproduct of Bell&rsquo / s seminal work to distinguish, via a Bell test, quantum correlations fro...

Motivated by the recent replication and reproducibility crisis, Gelman and Carlin (2014, Perspect. Psychol. Sci., 9, 641) advocated focusing on controlling for Type S/M errors, instead of the classic Type I/II errors, when conducting hypothesis testing. In this paper, we aim to fill several theoretical gaps in the methodology proposed by Gelman and...
Multiple tests arise frequently in epidemiologic research. However, the issue of multiplicity adjustment is surrounded by confusion and controversy, and there is no uniform agreement on whether or when adjustment is warranted. In this paper we compare frequentist and Bayesian frameworks for multiple testing. We argue that the frequentist framework ...

Stepwise regression building procedures are commonly used applied statistical tools, despite their well-known drawbacks. While many of their limitations have been widely discussed in the literature, other aspects of the use of individual statistical fit measures, especially in high-dimensional stepwise regression settings, have not. Giving primacy ...
Táto práca popisuje parametrický štatistický test ANOVA s ohľadom na jeho predpoklady a zvláštnosti s ním spojené. Prvá kapitola popisuje základné definície a metódy používané pri analýze rozptylu. V druhej kapitole sa zameriavame na predpoklady samotného testu a ďalšie postupy pri ich nesplnení. Posledná kapitola je venovaná porovnaniu dvojvýberov...

Wraz ze stale rosnącą liczbą badań w dziedzinie hematologii, znajomość metod statystycznych wykorzystywanych w analizie i interpretacji wyników stała się niezbędnym narzędziem pracy klinicystów. W artykule omówiono najczęściej stosowane testy statystyczne oraz zdefiniowano punkty końcowe stosowane podczas raportowania rezultatów badań klinicznych. ...
