Errors in a program for approximating confidence intervals (Letter to the Editor)

What is it about?

A previous article presented an SPSS program that contained nontrivial errors. Most notably, omitting square roots from certain computations resulted in radically inaccurate confidence intervals in the programmer's own provided example. The present letter urges that the program should not be used as written, and that software should be thoroughly vetted before it is disseminated for professional use.
