Geosciences, 2020 Geomathematics is extremely important in geosciences, particularly in the geology. The key for any geomathematical analysis is the definition of a typical model to be applied for further prognosis, either through deterministic or stochastic approaches ...

Bayesian detection of piecewise linear trends in replicated time-series with application to growth data modelling [PDF]
The International Journal Of Biostatistics, 2019, 2017 We consider the situation where a temporal process is composed of contiguous segments with differing slopes and replicated noise-corrupted time series measurements are observed. The unknown mean of the data generating process is modelled as a piecewise linear function of time with an unknown number of change-points.

Common pitfalls in statistical analysis: Intention-to-treat versus per-protocol analysis
Perspectives in Clinical Research, 2016 During the conduct of clinical trials, it is not uncommon to have protocol violations or inability to assess outcomes. This article in our series on common pitfalls in statistical analysis explains the complexities of analyzing results from such trials ...

Pitfalls in statistical analysis – A Reviewers' perspective
Indian Journal of Rheumatology, 2020 Statistics are a quintessential part of scientific manuscripts. Few journals are free of statistics-related errors. Errors can occur in data reporting and presentation, choosing the appropriate or the most powerful statistical test, misinterpretation or ...

Tests for strict monotonic trend in bio-medical dose-response relationships (respective concentration-response or exposure-response relationships) -- a biostatistical perspective [PDF]
arXiv, 2023 Evidence of a global trend in dose-response dependencies is commonly used in bio-medicine and epidemiology, especially because this represents a causality criterion. However, conventional trend tests indicate a significant trend even when dependence is in the opposite direction for low doses when the high dose alone has a superior effect.

Biostatistics: a fundamental discipline at the core of modern health data science
Medical Journal of Australia, 2019 Every year, Australia's National Health and Medical Research Council (NHMRC) spends around $800 million on medical and public health research,1 much of which depends critically on the correct analysis and interpretation of data.

An approach theoretic version of Anscombe's theorem with an application in biostatistics [PDF]
arXiv, 2016 We establish an approach theoretic version of Anscombe's theorem, which we apply to justify the use of confidence intervals based on the sample mean after a group sequential trial.
