(deprecated) Returns the confidence interval limits of the conditional mean forecast.
Syntax
GARCH_FORECI(X, Sigmas, Order, mean, alphas, betas, innovation, Nu, T, alphalevel, upper)
 X
 is the univariate time series data (a one dimensional array of cells (e.g. rows or columns)).
 Sigmas
 is the univariate time series data (a one dimensional array of cells (e.g. rows or columns)) of the last q realized volatilities.
 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 GARCH model mean (i.e. mu).
 alphas
 are the parameters of the ARCH(p) component model (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 function of 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)  Nu
 is the shape parameter (or degrees of freedom) of the innovations/residuals probability distribution function.
 T
 is the forecast time/horizon (expressed in terms of steps beyond end of the time series).
 alphalevel
 is the statistical significance level. If missing, a default of 5% is assumed.
 upper
 If true, returns the upper confidence interval limit. Otherwise, returns lower limit.
upper description 0 return lower limit 1 return upper limit
Warning
GARCH_FORECI() function is deprecated as of version 1.63: use GARCH_FORE function instead.
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 significance level (i.e. $\alpha$) must be greater than zero and less than one. Otherwise, a #VALUE! is returned
 The number of steps must be greater than zero. Otherwise, a #VALUE! is returned

Formula  Description (Result) 

=GARCH_FORE($B$2:$B$32,1,$D$3,$D$4:$D$5,$D$6,1)  Forecasted conditional mean at T+1 (0.160) 
=GARCH_FORECI($B$2:$B$32,1,$D$3,$D$4:$D$5,$D$6,,,1,5%,1)  Upper confidence interval for forecasted value at T+1 (1.798) 
=GARCH_FORECI($B$2:$B$32,1,$D$3,$D$4:$D$5,$D$6,,,1,5%,0)  Lower confidence interval for forecasted value at T+1 (2.118)
