Hi all,
I am working a non-parametric residual boostrap.
I have estimated my two data generating proceses, and thus have two vectors of disturbance terms.
From these two I need to draw (in pairs) with replacement.
Anyone who can help me?

Here's one possible way.
V1 and V2 represent your original data vectors.
N = 50;
NPAIRS = 20;
V1 = rand(N,1);
V2 = rand(N,1);
pairIndex = randi(N,[NPAIRS 1]);
pairArray = [V1(pairIndex), V2(pairIndex)]
