(1) Predicting missing values in spatio-temporal satellite data

  • predictions are obtained with selecting subsets, sorting procedures, and quantile regression
  • the workload can be distributed to several computers
  • the method is available in the R package gapfill

(2) 64-bit sparse matrices with the R package spam

  • spam and spam64 enables matrices with more than 2^31 non-zero elements
  • dotCall64 is an enhanced interface to link R with compiled code
  • spam64 was tested with a non-stationary spatial model

(3) Bayesian inference and medical applications

  • assessment of inference methods for Bayesian hierarchical models
  • spatial models for areal count data
  • operating characteristics for Bayesian clinical trial designs
