Estimation of Effect
Effect, ,
is estimated using three different statistics : mean, median, and Wilcoxon.
Accordingly, we have three CC's which will perform each estimation. These
CC's give the estimate, pvalue, and 95% CI for the estimate. The CC's
are

TwoSample hypothesis test and confidence interval for the location parameter

As an example consider the above XY data set and corresponding output.
We can see that

is (0.0, 7.0).
When we have paired (dependent) samples the following CC gives results
equivalent to the above.
As an example consider the following data. Assume the data is observed
on twins who received two different treatments.
Y : 9 12 10 15 12
X : 7 5 14 6 8
Diff : 2 7 4 9 4
Suppose we are testing H_{0}
: X = Y versus H_{A}
: X < Y. The output given by the CC is
As we can see,
and the 95% CI for
is (1.0, 8.0).
