Can the q distribution be derived in terms of the normal, Student's
t, Chi-squared, and F distributions, which are available on my
calculator?

Approximates the quantile p for a studentized range
distribution having v degrees of freedom and r samples
for probability p, p.ge.0.90 .and. p.le.0.99

Calculates an initial quantile p for a studentized range
distribution having v degrees of freedom and r samples
for probability p, p.gt.0.80 .and. p.lt.0.995

Thanks, Ray! At first glance it looks like it may be too complicated
for my calculator, but I'm going to look more closely in hopes of
finding blocks of code that can be replaced by native TI functions.

Thanks also in general for pointing me toward this library of
algorithms!
