Could someone please give a brief explanation, or pointer to an explanation,
of the following error:

> arima(ts.growth, order = c(1,0,0),include.mean=T)
Error in arima(ts.growth, order = c(1, 0, 0), include.mean = T) :
        non-stationary AR part from CSS

and why it does not arise with

> arima0(ts.growth, order = c(1,0,0))

Many thanks
