I have a sample of outcomes of my algorithm and would like to test to some degree of confidence if it differs from zero.
I know I can use a 1-sample t-test (as in https://docs.scipy.org/doc/scipy/reference/generated/scipy.stats.ttest_1samp.html), but I am wondering: does a non-parametric analogue exists?
I seem to understand that Mann Whitney U and Wilcoxon signed rank both work on 2 samples. Is this the case?
(questions are in bold)
Thanks in advance for any help :)
