Is the difference in coefficients on the lagged variable in the equations below the result of the solution algorithm? I think they should be exactly the same. I know the intercepts will differ. Thanks.

Re: Difference between AR1 and lagged variable coefficients
If you use CLS as the estimation method for ARIMA, then the coefficient on the AR term and the lagged dependent term will be the same. The coefficient on the constant will not.
If you use GLS or ML as the estimation method, all bets are off.

Further, the default AR estimation method is ML.
