#' @title Data on a circle
#' @description TIny sample of values on circle of circumference 1.
#' Used to illustrate that moving these values around the circle (eg.
#' by subtracting 0.25 from all of them, which, in a clockwise orientation, will change the origin from
#' North to East) the statistics V and U-squared will not change, even though the others
#' change.
