Dear forum,
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)$pred)
}
}
this one works. but I want to "save" my results in a matrix or a data.frame.
my second code:
foreL<-8
b0f<-matrix(nrow=9, ncol=foreL)
for(i in 1:9){
for(ar.ord in 1:3){
for(ma.ord in 1:3){
b0f[i,]<-c(predict(arima(para_qtr[1:(n-8),1],order=c(ar.ord,1,ma.ord)),
n.ahead=foreL)$pred)
}
}
}
sure- this one doesn't work. the matrix b0f only consists of the forecast of
the ARIMA(3,1,3)-model. I need the forecasts of ARIMA(1,1,1), ARIMA(2,1,1)
ARIMA(3,1,1), ARIMA(3,1,2) and so on ad nauseam in the lines of the b0f
matrix.
I would be glad if someone could help me.
best regards, fred
