GARCH and irregularly spaced data

  • Meddahi, Nour
  • Renault, Eric
  • Werker, Bas

An exact discretization of continuous time stochastic volatility processes observed at irregularly spaced times is used to give insights on how a coherent GARCH model can be specified for such data. The relation of our approach with those in the existing literature is studied.
