Supose I have a matrix X[n,n] dimension I would like to calculate the product of the vectors Y=X[1,n]*X[n,1] Then I would like to run the following operation H=if(Y>0) {H[,1]=1} The problem is that the condition "if" works only for the

Dear all, My name is Guillermo I'm trying to write a short program to find all the possible combination in fitting an ARIMA Model. My script is the following: n=rnorm(100)+5 Aux.M=matrix(NA,nrow=100,ncol=2) L=1 for(i in 0:2) {for(j in 0:2) {for(k in 0:2) Aux.M[L,2]=arima(n,order=c(i,j,k),include.mean=TRUE)$aic x1=paste("AR=",i,sep=" ")
