Dear Listers,
I am currently using stata 7.0 SE. My concern is that the ARCH command
in stata maybe not stable. I have run some garch estimation many times. the
estimation will give error message occationly, depend the sample size. When
i add changed more samples, even a few, the ML works. I wonder if i can
preset the initial values for the coefficient but failed. I am writing this
letter to see if any of you have also encounter such problems and whether
stata 8.0 is more powerful in GARCH estimation.
thanks
Lee Chuntao
