Dear fellows !
I made two sample Wilcoxon-ranksum-test
/ to show that two independent samples are from same distribution = H0/
with following results: m ... men W ... woman
-
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(gender==m) = dosis(gender==W)
z = -0.354
Prob > |z| = 0.7236
-
because of theorie in my books and referencebook in Stata is not
"exactly the same" I want to assure about denotation of results ?
z= -0.354 is check-value - o.k.
but I don't understand : Prob > |z| = 0.7236
Confidence-intervall that H0 is right - is ~72% ??
but what does mean : Prob > |z| ?
any help will be appreciated very much
