Display parameter estimation results for EGARCH models




print(fit,VarCov) displays parameter estimates, standard errors, and t statistics for a fitted EGARCH model.

Input Arguments


Estimated egarch model object, as output by estimate.


Estimation error variance-covariance matrix, as output by estimate. VarCov is a square matrix with a row and column for each parameter known to the optimizer when model was fit. Known parameters include all parameters estimated as well as all parameters held fixed during optimization. Rows and columns associated with any parameters held fixed contain 0s.

The parameters in VarCov are ordered as follows:

  • Constant

  • Nonzero GARCH coefficients at positive lags

  • Nonzero ARCH coefficients at positive lags

  • Nonzero leverage coefficients at positive lags

  • Degrees of freedom (t innovation distribution only)

  • Offset (models with nonzero offset only)

Print EGARCH Estimation Results

Print the results from estimating an EGARCH model using simulated data.

Simulate data from an EGARCH(1,1) model with known parameter values.

modSim = egarch('Constant',0.01,'GARCH',0.8,'ARCH',0.14,...
rng 'default';
[V,Y] = simulate(modSim,100);

Fit an EGARCH(1,1) model to the simulated data, turning off the print display.

model = egarch(1,1);
[fit,VarCov] = estimate(model,Y,'print',false);

Print the estimation results.
