R help - May 2009 - transformation and outliers

Dear R people

I ask again


1.	Is there a published reference presenting the normal score
transformation? Is there a published paper (in any field) using that
transformation in the analysis of data?

And this is a new question


2.	The ?outliers? library has a function called ?rm.outlier?. It offers
the option of either removing one outlier (the largest or the smallest) or
replacing the identified outlier by the mean or median of the data. Does anyone
know of a published paper introducing that particular approach (replacing the
outlier by the group?s mean/median)?

Cheers

Fer

Dunno, but I'd search for "Normal Scores Test", AKA van der
Waerden's
Test, in books dealing with nonparametric tests.  It comes out in a 
natural way as the score test in a model  where you assume that you have 
normally distributed data with a location shift, but transformed by an 
unknown monotone transformation.
