Python wilcoxon: unequal N

问题

Rs wilcox.test can take different length vectors, but the wilcoxon from scipy.stats cannot: I get an unequal N error message.

from scipy.stats import wilcoxon
wilcoxon(range(10), range(12))

Is there a way to get Rs behavior in Python?

回答1:

According to the R docs:

Performs one- and two-sample Wilcoxon tests on vectors of data; the latter is also known as ‘Mann-Whitney’ test.

So just use

from scipy.stats import mannwhitneyu
mannwhitneyu(range(10), range(12))
# (50.0, 0.26494055917435472)
