Keywords:

  • statistical inference - autocorrelation check for white noise;
  • problem of selecting appropriate GARCH or ARMA-GARCH model - for given observations X1, …, Xn of centered stationary process;
  • autocorrelation check for white noise;
  • sample autocorrelations (SACRs);
  • behavior of sample autocorrelations of GARCH process;
  • standard portmanteau test - checking that data is a realization of a strong white noise, Ljung and Box (1978);
  • sample partial autocorrelations (SPACs) - SPACs and their significance bounds;
  • identifying ARMA orders of ARMA-GARCH;
  • order determination, based on sample and partial autocorrelations in mixed ARMA(P, Q) model - not an easy task;
  • Box–Jenkins methodology for ARMA models - also adapted to GARCH(p, q) models
