Returns an array of the standardized residuals for the fitted EGARCH model.
Syntax
X is the univariate time series data (a one dimensional array of cells (e.g. rows or columns)).
Order is the time order in the data series (i.e. the first data point's corresponding date (earliest date=1 (default), latest date=0)).
Order  Description 

1  ascending (the first data point corresponds to the earliest date) (default) 
0  descending (the first data point corresponds to the latest date) 
mean is the EGARCH model mean (i.e. mu).
alphas are the parameters of the ARCH(p) component model (starting with the lowest lag).
gammas are the leverage parameters (starting with the lowest lag).
betas are the parameters of the GARCH(q) component model (starting with the lowest lag).
innovation is the probability distribution model for the innovations/residuals (1=Gaussian (default), 2=tDistribution, 3=GED).
value  Description 

1  Gaussian or Normal Distribution (default) 
2  Student's tDistribution 
3  Generalized Error Distribution (GED) 
v is the shape parameter (or degrees of freedom) of the innovations/residuals probability distribution function.
Remarks
 The underlying model is described here.
 The time series is homogeneous or equally spaced.
 The time series may include missing values (e.g. #N/A) at either end.
 The number of gammacoefficients must match the number of alphacoefficients.
 The number of parameters in the input argument  alpha  determines the order of the ARCH component model.
 The number of parameters in the input argument  beta  determines the order of the GARCH component model.
 The standardized residuals have a mean of zero and a variance of one (1).
 The EGARCH model's standardized residuals is defined as:
$$\epsilon_t = \frac{a_t}{\sigma_t} $$
$$a_t = x_t  \mu $$
Where:
 $\epsilon $ is the EGARCH model's standardized residual at time t.
 $a_t$ is the EGARCH model's residual at time t.
 $x_t$ is the value of the time series at time t.
 $\mu$ is the EGARCH mean.
 $\sigma_t$ is EGARCH conditional volatility at time t.
