[Rd] Stroring and extracting AICs from an ARIMA model using a nested loop

Hello I am trying to extract AICs from an ARIMA estimation with different combinations of p & q ( p =0,1,2,3 and q=0,1.2,3). I have tried using the following code unsucessfully. Can anyone help? code: storage1 <- numeric(16) for (p in 0:3){     for (q in 0:3){       storage1[p]  <- arima(x,order=

ector("list", 16) i <- 0L for(p in 0:3){   for(q in 0:3){     i <- i + 1L     storage1[[i]] <- arima(etc)   } } lapply(storage1, '[[', "aic")  # get the aic's. Maybe sapply is better it will return a vector. Hope this helps, Rui Barradas Às

;> for(q in 0:3){ >> storage1[p + 1, q + 1] <- arima(etc)$aic >> } >> } >> 2. define storage1 as a list. >> storage1 <- vector("list", 16) >> i <- 0L >> for(p in 0:3){ >> for(q in 0:3){ >> i <- i + 1L >
