Find the radius of a 100(1-\alpha)
% confidence region for the
projected mean based on a result from directional statistics.

## S3 method for class 'Q4'

Compute the radius of a 100(1-\alpha)
% confidence region for the
central orientation based on the projected mean estimator using the method
due to prentice1986. For a rotation specific version see
rancourt2000. The variability in each axis is different so each axis
will have its own radius.
prentice1986, rancourt2000
Radius of the confidence region centered at the projected mean for each of the x-, y- and z-axes.
