2012-9 Writing grid Extensions
New hook functions, makeContext() and makeContent(), have been added to the grid graphics package. These functions allow an alternative approach to developing custom grobs when …
2012-8 Meta-analysis of a rare-variant association test
Genome-wide assocation studies have often been carried out by meta-analysis rather than by pooling individual-level data. For one-dimensional parameter estimates and the corresponding tests of …
2012-7 A Structured Approach for Generating SVG
The gridSVG package exports grid images to an SVG format for viewing on the web. This article describes a new development in the way that …
2012-6 Working with the gridSVG Coordinate System
The gridSVG package exports grid images to an SVG format for viewing on the web. This article describes new features in gridSVG that allow grid …
2012-5 Voronoi Treemaps in R
A Voronoi Treemap is a visualisation tool for displaying data with a hierarchical structure. This article describes an open source implementation of Voronoi Treemaps in …
2012-4 Two-sample rank tests under complex sampling
Rank tests are widely used for exploratory and formal inference in the health and social sciences. With the increasing use of data from complex survey …
2012-3 An empirical-process central limit theorem for complex sampling under bounds on the design effect
Uniform central limit theorems (`Donsker theorems’) have been widely useful in semiparametric statistics, both under iid sampling and for stationary sequences and random fields. Only …
2012-2: Two-phase subsampling designs for genomic resequencing studies
Targeted resequencing of DNA at specific genes or other genomic loci is now feasible for hundreds or thousands of samples, and costs for larger-scale resequencing …
2012-1: Partial Likelihood Ratio Tests for the Cox model under Complex Sampling
We develop an analogue of the likelihood ratio test for Cox proportional hazards models fitted to sample survey data. We look at methods for computing …
