this implementation. For this reason, most comparisons in R are made
against PairedData's method.

Rather than providing the input and output for all evaluations, here is
a representative example:
> library(PairedData)
> a <- c(1, 2, 3)
> b <- c(1.1, 2.9, 4.2)
> options(digits=16)
> yuen.t.test(a, b, tr=.2)

    Two-sample Yuen test, trim=0.2

data:  x and y
t = -0.68649512735573, df = 3.4104431643464, p-value = 0.5361949075313
alternative hypothesis: true difference in trimmed means is not equal
to 0
95 percent confidence interval:
 -3.912777195645217  2.446110528978550
sample estimates:
