Mike,
Attached is an R function to do this, along with an example that will
reproduce the MathCad plot shown in your attached paper. I haven't checked
it thoroughly, but it seems to reproduce the MathCad example well.
Ravi.

According to the paper I cited, there is controversy over the
sufficiency of Hinkley's solution, hence their proposed more complete
solution.
