@ChadFulton sorry to bother again.
this is a relevent question to #8460 when i working on a workaround to set bounds on sarimax.fit, i could use the confidence intervals from fit results by mlefit, but all i got is nans, including mlefit.bse.
is this normal? what should i do to get resonable results?
