Information Geometry of GARCH Model

  • School of Sciences, Beijing Institute of Technology, Beijing 100081, China

  • Received Date:2008-05-09
    Abstract
  • A statistical manifold of non-exponential type coming from a model for economics describing stock return process is constructed, with its geometric structure investigated and both Gaussian curvatures and mean curvatures of its curved exponential submanifolds deducted. A few graphs describing relevant scalar curvature, mean curvature and Gaussian curvature are also introduced.
