Dear R-helpers,
I need to read some data from output of garchFit in fGarch.
my model is garch(1,1) and i want to read
coefficients(omega,alpha,beta) and timeseries(x)  and conditional
SD(s). because i need them to use  in other formula.
for example :omega+x[1]+s[3]
and maybe i have several simulation then i need a general way  to read
them, not to read with my eyes for example the quantity of omega then
subsitute in formula.
Best.

Hello,

What a terribly asked question.
Let me rephrase it. You have a time series 'x' simulated with garchSim 
from package fGarch and have fitted a model using garchFit.
1. You want to extract the coefficients.
coef(fit)

2. You want the series of observations (simulated) and of conditional sd.
x$garch
x$sigma

Hope this helps,
