  • Outline
  • The SAEM algorithm
  • The MONOLIX group
  • MONOLIX use in academia

3
  • 1. The SAEM Algorithm
  • An algorithm developed by mathematicians from
    French universities
  • Delyon, Lavielle Moulines (1999). Convergence
    of a stochastic approximation version of the EM
    procedure. Ann Stat, 27 94-128.
  • with extention to nonlinear mixed effect models
  • Kuhn Lavielle (2004). Coupling a stochastic
    approximation version of EM with a MCMC
    procedure. ESAIM PS, 8 115-131.
  • Kuhn Lavielle (2005). Maximum likelihood
    estimation in nonlinear mixed effects models.
    Comput Stat Data Analysis, 49 1020-1038.
  • which has proven theoritical convergence

  • 2. The MONOLIX Group (1)
  • Multidiciplinary academic working group
  • Created in October 2003 by M. Lavielle and F.
    Mentré
  • Involves members of various French academic
    institutions (Universities, INSERM, INRA,
    INRIA,)
  • International collaborations with several
    academic groups

5
  • The MONOLIX Group (2)
  • A common goal develop new methods for the study
    and use of nonlinear mixed effect models
  • Develop new methods/algorithms means
  • 1) Study their theoritical properties (and
    publish them)
  • 2) Implement them in sofwtare,
  • 3) Apply them to real problems (and publish
    them).

6
  • The MONOLIX Group (3)
  • Two main research projects
  • - estimation and model selection
  • - design optimisation
  • Two software
  • - MONOLIX
  • - PFIM
  • Main area of application
  • pharmacometrics

8
  • Main statistical developments
  • Models with ordinary or stochastic differential
    equations

  • COMMENTS
  • Useful program, Bravi!
  • Great piece of software , easy to use, very
    stable
  • Delighted with the tools it provided
  • Much easier to use than WinNonLin V
  • Shift the PhD students from NONMEM to MONOLIX
  • Great program for teaching basic concepts of
    population modelling
  • Reinforce concept difficult to teach using NONMEM
  • A useful tool especially for limited sampled data
    sets seen in pediatrics
  • User-friendly
  • Much better at handling sparse data
  • A treasure for the scientific community
  • Unbelievable thats it's free
  • Great tool! Very pedagogical
