Quantiles of the Studentized Range distribution

Quantiles of the Studentized Range distribution

Post by Wolfgang Hitz » Wed, 16 Sep 1998 04:00:00

Hi overthere,

I am looking for a formula to compute the quantiles of the Studendized
Range distribution with parameter r and v.

If the original function is not available, I would also appreciate an
If the quantiles are not available, but the probability density or/and
the cumulative density,
this would also help.

I would like to compute the quantiles with Mathematica 3.0.1.

Any help is strongly appreciated,

best wishes to you

Hi Wolfgang,

I have a Mathcad worksheet which calculates the probability density and uses
the solver to get the quantiles.
Let me know if you want it. A free Mathcad browser is available at the
Mathsoft web site.

1. Quantiles for Noncentral Distributions?

Hello everyone,

I have been becoming interested in noncentral distributions, namely
those of the t, F, and chi sq distributions.  I would guess that there
is a way in SAS to derive the quantiles of these distributions if one
knows the degrees of freedom and noncentrality parameter value.
However, I have been unable to locate information on how one would go
about finding these quantiles.  Is there even a way to do this in SAS?
If not does anyone know other options for obtaining these values?

I'm using SAS V8 on Windows 98SE.

Thanks for any help and have a nice day,
