MATLAB: What statistical test is available in matlab for unbalanced samples other than ttest

statistical testStatistics and Machine Learning Toolboxttest

I have two data sets that have different sizes and need to do statistical test. ttest can handle unbalanced ttest but because of its assumptions (from normal distribution and same variance) I want to try more statistical test. for example kruskalwallis only works fr balanced data.

One possibility is the Wilcoxon rank sum test.

The paired t-test says nothing about correlation. (The 'unequal' flag is about the variances.)

Consider:

t = linspace(0, 10*pi);
v1 = sin(t);
v2 = 2*rand(size(t))-1;
[h,p] = ttest2(v1, v2)
h =
     0
p =
     0.6819

It does indicate if the means are different (rejecting the null hypothesis) at a specific significance.

EDIT — Added example.

Try cumsum() and use Inverse Transform Sampling.

Also see RANDRAW to see how the author generates dozens of distributions.
