Hi everyone,
I am trying to vectorize a function on the functions block. However, at some point I need to make a decision based on an elementwise comparison. Something like:
vector foo(vector y) {
real quantity;
int N = num_elements(y);
vector[N] z = if (y < quantity) {
do_something(y);
} else {
do_nothing(y);
}
return z;
}
Is there a workaround to implement this sort of thing in Stan? Or at the moment the only way to go would be to use a for loop on every element of my vector?
Thanks,
Tiago
