Using the nationally representative Slan dataset of 2007 we analyse the relationship between self-reported and measured BMI. We find that self-reported BMI significantly underestimates obesity rates and suggest that the traditional threshold of 30 should be adjusted downwards. We outline a...

A new multiple testing procedure, called the FDR<Subscript> L </Subscript> procedure, was proposed by Zhang et al. (Ann Stat 39:613–642, <CitationRef CitationID="CR12">2011</CitationRef>) for detecting the presence of spatial signals for large-scale 2D and 3D imaging data. In contrast to the conventional multiple testing procedure, the FDR<Subscript> L </Subscript> procedure...</subscript></citationref></subscript>

As biotechnology has made remarkable progress nowadays, there has also been a great improvement on data collection with lower cost and higher quality outcomes. More often than not investigators can obtain the measurements of many disease-related features simultaneously. When multiple potential...
