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...

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...

In several cases the same measurement is used as a marker for two or more population features, and it is useful to test whether this measurement has the same diagnostic effectiveness with respect to different features. In this paper we use the area under receiver operating characteristic curve...
