how do I transform this to a for loop
arima1 = arima(data.ts[1:200], order = c(1,1,1))
arima2 = arima(data.ts[5:205], order = c(1,1,1))
arima3 = arima(data.ts[10:210], order = c(1,1,1))
arima4 = arima(data.ts[15:215], order = c(1,1,1))
arima5 = arima(data.ts[20:220], order = c(1,1,1))
arima6 = arima(data.ts[25:225], order = c(1,1,1))
arima7 = arima(data.ts[30:230], order = c(1,1,1))
arima8 = arima(data.ts[35:235], order = c(1,1,1))

outputting arima models
sseq <- c(1, seq(5, 120, by = 5))
for(i in 1:length(sseq)){
assign(paste("arima", i, sep=""), arima0(data.ts[sseq[i]:(sseq[i]+115)],
order=c(1,1,1)))
}
pred1 = predict(arima1, n.ahead = 5, se.fit = TRUE)$pred
how do I traverse the arima models so I repeat the above prediction
