Prove central limit theorem
Afficher commentaires plus anciens
How do I make an attempt to prove the central limit theorm for following uniform variables? Their dimension are different and the size of the matrix, not necessarily has to be same.

Try this:
v = rand(1, 10)-0.5;
c{1} = v;
for k = 2:50
c{k} = conv(c{k-1},v);
end
figure
histogram(c{end}, 21)

Note that you won't theoretically "prove" the CLT by simple random sampling. A proof would require the use of limits.

‘prove’ = ‘illustrate’

Um, no. I must disagree. :)
If the two were equivalent, then a picture of a pile of gold would be as good as that pile of gold. A picture of piles of currency in my private bank vault might serve to convince you that I MIGHT be rich, but it would not be proof of fact.
An illustrative example is nice, and it may convince you there is some meat behind an idea. But it is not a proof.
