Using ranksum function

I have a distribution which is not normal and i want to use wilcoxon rank test to test if the median is =0;if the observations are in vector X can i run the test this way: [p,h]=ranksum(X,0)

Answer 1

[Oleg Komarov]

Use signrank:

p = signrank(x) performs a two-sided signed rank test of the null hypothesis that data in the vector x comes from a continuous, symmetric distribution with zero median, against the alternative that the distribution does not have zero median. The p value of the test is returned in p.

yes

doc ranksum

will confirm that the input arguments need not be equal
