Non-Gaussian distributions under scrutiny

Imputing continuous data under some non-Gaussian distributions

There has been a growing interest regarding generalized classes of distributions in statistical theory and practice because of their flexibility in model formation.Multiple imputation under such distributions that span a broader area in the symmetry–kurtosis plane appears to have the potential of better capturing real incomplete data trends. In this article, we impute continuous univariate data...

Under Scrutiny

Folic acid under scrutiny

A consideration of the absorption and metabolism of folic acid in human subjects is timely, owing to the recent recommendation by the UK Government’s Scientific Advisory Committee on Nutrition that a mandatory folic acid fortification programme be implemented in the UK. In this issue of the British Journal of Nutrition, Wright et al. take us through the processes of absorption and metabolism of...

ContSys under Ontological Scrutiny

EN ISO 13940, commonly known as ContSys, is an international standard that provides a system of concepts to support continuity of care and semantic interoperability of information systems. ContSys provides domain-specific terms, definitions and relationships, but was not developed as an ontology. Nevertheless, we think that it might benefit from the application of more formal, ontological analy...
