1 DEAL: Learning Bayesian Networks in R Susanne G. Bøttcher Claus Dethlefsen Aalborg University and Novo Nordisk A/S

2 The DEAL Team Susanne G. Bøttcher (alma@math.auc.dk) Soon to finish Ph.D. Supervisor: Steffen Lauritzen Claus Dethlefsen (dethlef@math.auc.dk) Recent Ph.D. within state space models. Supervisor: Søren Lundbye-Christensen Both supported by Novo Nordisk A/S August 2001-August 2003

3 History of DEAL 1997-2002 Susanne’s Ph.D.: Development of theory 2000-2001 Preliminary software in S-Plus (Susanne) Nov/Dec 2001: Prototype of DEAL (Susanne/Claus) Aug 2002: DEAL is released (Susanne/Claus)

4 What can DEAL do for us?
