Alternative to slow double for() loop
...or() loop,
and was wondering if anybody could suggest an alternative to using this
double loop which would speed things up.
The program looks like this:
for (j in 1:m) {
for (i in 1:n) {
times<-comp.list[[j]][which(comp.list[[j]]$V1==i),]
T<-ncol(times)
Y<-times$V2
Y<-data.matrix(Y)
cova<-subset(times, select=V3:V16)
cova<-data.matrix(cova)
pr<-exp(cova%*%beta)/(1+exp(cova%*%beta))
dipr<-diag(c(pr[1,1], pr[2,1]))
dipr1<-dipr-(pr%*%t(pr))
A<-diag(c(dipr1[1,1],dipr1[2,2]))
D<-t(cova)%*%A
V<-A
u1<-D%*%solve(V)%*%(Y-pr)
u<-u+u1
usq<-usq+(u1%*%t(u1))
