DESCRIPTION:Detecting interactions when analyzing data sets created by lar
 ge cohort or association studies is becoming increasingly important in Bio
 statistics. Investigating complex dependence structures within a linear mo
 delling framework is not straightforward due to the difficulty in searchin
 g an unwieldy large space of competing models. One approach for reducing t
 he dimensionality of the problem is to utilize a Bayesian modelling approa
 ch based on the Dirichlet process. We investigate the relation between the
  Dirichlet process and linear modelling\, and discuss the utility of the D
 irichlet process for the exploration of high order interactions\, especial
 ly when sparse data are analysed.
