Dear all R-users,
I wanted to fit a Garch(1,1) model to a dataset by:
>garch1 = garch(na.omit(dat))
But I got a warning message while executing, which is:
>Warning message:
>NaNs produced in: sqrt(pred$e)
The garch parameters that I got are:
> garch1
Call:
garch(x = na.omit(dat))
Coefficient(s):
a0 a1 b1
1.212e-04 1.001e+00 1.111e-14
Can any one please tell me that why got this message? What is the remedy?
Thanks and Regards
