[R] Gsarima and Method

[Lorenzo Isella]

Dear All,
While tuning some time series model with gsarima (which is primarily a
wrapper for arima) from the astsa package, I encounter the following
error message

Error in stats::arima(xdata, order = c(p, d, q), seasonal = list(order
= c(P,  :
  non-stationary seasonal AR part from CSS

According to what I found here

http://bit.ly/1QmTJtu

for a case with the arima function, the solution is to add method="ML"
to the call to arima, but it is not clear at all to me how to
introduce it in the sarima function.
Any help is appreciated
Regards

Lorenzo
