SABRE in R: An OGSA Component-Based Approach to Middleware for Statistical Modelling

Principal Investigator – Prof. Rob Crouchley, Lancaster University
Contact – r.crouchley @ Lancaster.ac.uk

The aim of this project was to demonstrate the effectiveness of an Open Grid Services Architecture component-based approach to middleware for handling some large-scale statistical modelling problems currently confronting e-social scientists.
(SABRE is a program for the statistical analysis of binary, ordinal and count recurrent events. Such data are common in many surveys either with recurrent information collected over time or with a clustered sampling scheme.)

The key objectives of the project were:

  • To develop a serial and parallel OGSA implementation of SABRE with extended facilities for multilevel multiprocess modelling
  • To make the source code of the original and parallel versions of SABRE freely available
  • To compare the performance of the sequential version of SABRE and equivalent MLwiN and STATA (GLAMM) analyses with that of the parallel version of SABRE using two substantive pieces of research as illustrations
  • To make the serial and parallel versions of SABRE freely available as R Objects for use in the R statistics and computing system
  • To explore the possibility of a Web portal to SABRE and SABRE within R
