Although I know that "ts package" is preliminary, I wanted to compare the
results from R and SPSS. I ran ARIMA(2,1,2) in both softwares. I got NaN in
standard errors of coefficients from R and real figures from SPSS. I changed
"delta" in R to match that used by SPSS, I received results with no NaNs but
different from those from SPSS specially in MA coefficients. They came out
negative numbers while positive from SPSS.
