I am trying to understand sampling techniques but I am stuck on jacknife. Can somebody explain how jacknife sampling works? How can I see the samples? or this is completely different than I thought? Thanks for the help.
load ('wine.txt'); format shortG;X = wine(:,(1:13));Y = wine(:,14);% [~,bootsam] = bootstrp(2,[],X,Y);
% [s,idx] = datasample(wine,100,'Replace',false);
js = jackknife(@corr,X,Y);
