Re: uniTimeSeries.arima results are different (and worse) than statsmodels SARIMA

Thanks Rajesh. I was wondering if the signs on the parameter estimates were flipped. I know that other software (ie. SEATS) uses a different standard format for the polynomial and uses parameter estimates with signs that are reversed from the format used in proc arima and other program.
