st: RE: save p-values from Kruskal-Wallis-test

["Ken Clark" <Msraskc@fs1.ec.man.ac.uk>]

Dear All

On yesterday's list, Gerhard Schoen asked about p-values for the 
Kruskal-Wallis test.  David Harrison replied suggesting 

. display chi2tail(r(df), r(chi2))

while Kieran McCaul suggested

. display chi2tail(`r(df)', `r(chi2)')

That is, Kieran puts single quotes (presumably denoting a local 
macro) around the returned results.

My questions is simply whether, or under what circumstances, this 
second usage is better?  Would it ever give a different answer to 
the first usage?

Thanks

Ken
