Hello, all!
I need help on these two problems:
1) If I want to randomly draw numbers from standard normal (or other
distributions) in loops e.g.:
ty=0; ks=0
for (i in 1:5) {
set.seed(14537+i)
k<-rnorm(1)
ks[i]<-.3*k+.9
if (ty==0) {
while ((ks<.2)||(ks>3)) {
#set.seed(13237+i*100)
k<-rnorm(1)
ks[i]-.3*k+.9 }
}
}
....
....
....
}
Question: Here I draw initial a, then if the drawn initial a satisfied 2
conditions I redraw a. I set.seed(13237) in the first draw of a, should I
set.seed() in the redraw part?
2) I also have more loops after this i loop that also draw from normal(0,1). I
want to randomly draws from normal(0,1) for loop j (inside loop j I draw
another random numbers from N(0,1))
My question: Should I or shouldn't I set seed again and again for each loop?
Why or why not.
I guess this problem concerned about setting seed as I want to have different
number for each i.
Thanks!
Deana
