mannWhitneyUTest
Syntax
mannWhitneyUTest(X, Y, [correct=true])
Arguments
X is a numeric vector.
Y is a numeric vector.
correct is a Boolean value indicating whether to consider continuity correction when calculating the p-value. The default value is true.
Details
Perform the Mann-Whitney U test on X and Y. It returns a dictionary object with the following keys:
-
stat: A table containing p-values under three different alternative hypotheses
-
correct: Whether to consider continuity correction when calculating p-value
-
method: The string "Mann-Whitney U test"
-
U: U statistic
Examples
mannWhitneyUTest(5 1 4 3 5, 2 4 7 -1 0 4);
