x<-c(-1.873....,-0.121)  # 23 numerics;
  x.arma12 <- armaFit(x ~ arma(1,2))
  #estimates y[t]= -0.11465 - 0.23767 y[t-1] - 0.14230 e[t-1] -0.85770 e[t-2] + e[t];
   
  # ? how to predict 46 steps ahead based on 23 data points? 
  # the following doesn't work since n is in armaSim rather than armaFit;
  predict(x.arima12, n.ahead=46) 
   
  # Thanks
