The plot indicates that it is primarily large negative shocks that are driving the departure from normality. You should add the C to your specification if you wish to include a constant. Because the variance appears in a non-linear way in the likelihood function, the likelihood function must be estimated using iterative algorithms. We will specify our mean equation with a simple constant:. To specify the form of the conditional distribution for your errors, you should select an entry from the Error Distribution dropdown menu. You can enter the specification in list form by listing the dependent variable followed by the regressors. In the Variance regressors edit box, you may optionally list variables you wish to include in the variance specification. Using the Options dialog, you can also set starting values to various fractions of the OLS starting values, or you can specify the values yourself by choosing the User Specified option, and placing the desired coefficients in the default coefficient vector. Once you have filled in the Equation Specification dialog, click OK to estimate the model.
ARCH term is the square of past residual factors (e2) while GARCH is the past volatility (variance H) for general GARCH model and in the case. Can any one help in modelling GARCH/EGARCH in Eviews or Stata??
I am including a PPT to explain how to model any GARCH type model in Eviews. You can control the number of determinant 'NVARS=7' to get better estimation. Using Eviews, how do I interpret the resulting coefficients in the conditional variance equation of an I have attached a sample EGARCH output for reference.
This option is only available if you choose the conditional normal as the error distribution.

Instead of using the built-in QQ-plot for the t -distribution, you could instead simulate a draw from a t -distribution and examine whether the quantiles of the simulated observations match the quantiles of the residuals this technique is useful for distributions not supported by EViews.
The dialog will change to show you the ARCH specification dialog. Your next step is to specify your variance equation. Note that the parameter estimates will be unchanged if you select this option; only the estimated covariance matrix will be altered.

|If you have a more complex mean specification, you can enter your mean equation using an explicit expression. To specify the form of the conditional distribution for your errors, you should select an entry from the Error Distribution dropdown menu.
As with other iterative procedures, starting coefficient values are required. When the assumption of conditional normality does not hold, the ARCH parameter estimates will still be consistent, provided the mean and variance functions are correctly specified.

We will specify our mean equation with a simple constant:. EViews provides you with access to a number of optional estimation settings.
EGARCH Model Diagnostics. The correlogram for the standardized squared. To estimate this model, open the GARCH estimation dialog, enter the The top portion of the output from testing up-to an ARCH(7) is given by.
To estimate an ARCH or GARCH model, open the equation specification dialog by selecting Quick/Estimate Equation, by selecting.
Select ARCH from the method dropdown menu at the bottom of the dialog. This is expected, as the previous QQ-plot suggested that, with the exception of the large negative shocks, the residuals were close to normally distributed.

Our experience has been that GARCH models initialized using backcast exponential smoothing often outperform models initialized using the unconditional variance. EViews displays the results of the estimation procedure. In the latter two cases, you will be prompted to enter a value for the fixed parameter.

Introduction to EViews Chapter 1. Introduction to EViews EViews is a simple. For example: "" "" will always be interpreted as January 3. EViews Workshop Series Agenda.

ARCH models are estimated by the method of maximum likelihood, under the assumption that the errors are conditionally normally distributed.

You should use this option if you suspect that the residuals are not conditionally normally distributed. When we previously estimated a GARCH 1,1 model with the data, the standardized residual showed evidence of excess kurtosis. The output is presented below:. Note that the parameter estimates will be unchanged if you select this option; only the estimated covariance matrix will be altered.
To see how the model might fit real data, we examine static forecasts for out-of-sample data.

|As with other iterative procedures, starting coefficient values are required.
Note that we have modified the QQ-plot slightly by setting identical axes to facilitate comparison with the diagonal line. You should use this option if you suspect that the residuals are not conditionally normally distributed. Note that measures such as may not be meaningful if there are no regressors in the mean equation. The likelihood functions of ARCH models are not always well-behaved so that convergence may not be achieved with the default estimation settings.
If you have a more complex mean specification, you can enter your mean equation using an explicit expression.
