One practical difference is that when you are modeling categorical data
you need to use non-parametric approaches, whereas you can use
parametric approaches with continuous data.  Ordinal data can sometimes
use parametric approaches but often has to use non-parametric
approaches.

Hello SAS-L,

I am new to this list. I am an inexperienced statistical modeler, just
beginning my work now.

I will be posting lots of questions on this list...SAS and statistically
related.

I would like to offer you my apologies if I offend some of you with my
simple SAS & STAT questions. I will learn eventually from you all and I
may even begin to ask difficult questions later on.

So, here is my first question:

When we are talking about parametric vs non-parametric approaches, when
it comes to statistical formulas, modeling, etc., what are we talking
about?

Thank you.

Tom White (aka  tw  from now on)
