I would like to forecast e.g. with the arima-model. To figure out which
model works best I am going to predict with this models.
my first code:
for(ar.ord in 1:3){
for(ma.ord in 1:3){
print(predict(arima(para_qtr[1:(n-8),1],order=c(ar.ord,1,ma.ord)),
n.ahead=8)$pred)
}
}

my second code:
foreL<-8
b0f<-matrix(nrow=9, ncol=foreL)
for(i in 1:9){
for(ar.ord in 1:3){
for(ma.ord in 1:3){
b0f[i,]<-c(predict(arima(para_...
