I made two sample Wilcoxon-ranksum-test
/ to show that two independent samples are from same distribution = H0/
with following results:
-
    gender |      obs    rank sum    expected
-------------+---------------------------------
           m |   3.7e+05  1.397e+11   1.398e+11
           W |   3.7e+05  1.382e+11   1.382e+11
-------------+---------------------------------
    combined |   7.5e+05  2.780e+11   2.780e+11

unadjusted variance   8.636e+15
adjustment for ties  -1.316e+08
                     ----------
adjusted variance     8.636e+15

Ho: dosis(geschl1==m) = dosis(geschl1==W)
             z =  -0.354
    Prob > |z| =   0.7236
