Hello,

Below is a reproducible example to generate the output by using Dr. Young's R code on the above subject .   As commented below, the issue is that  part of the code (regtol.int and plottol) does not seem to work.

I would appreciate receiving your advice toward resolving the issue.

Thanks and regards,

Pradip Muhuri
