thankx to everyone for your valuable suggestions. one query regarding the
GARCH model.
I have applied the GARCH model for the same data that I send you all . and
my results coming like
Error in .sgarchfit(spec = spec, data = data, out.sample = out.sample, :
ugarchfit-->error: function requires at least 100 data
points to run
can you suggest something on it.
